If the older JDK isn't on your machine, you'd need to use the GUI and download the Java updater. The one closest to yours I could find was for Java 1.6.015 for Mac OS 10.5 (you didn't mention which Mac OS X version you were running): Java for Mac OS X 10.5 Update 5. I didn't see any for Mac OS X 10.6. After you have installed the JRE, you can start Java applets and applications by double-clicking JAR files, JNLP files, and by using the browser. Note that 32-bit browsers, such as Firefox in 32-bit mode, and Chrome, are not supported by the JRE. If you also plan to create Java applications, then install the Java Development Kit (JDK).

Compared with its rival Eclipse (http://www.elicpse.org) (both are open-source, so I don't know what are they competing for?), NetBeans provides seamless support for Java AWT/Swing, Java ME mobility pack, Java EE, and bundled with an excellent profiler for performance tuning.

NOTE (2018 Feb 01): NetBeans 8.2 might not work with JDK 9 at this moment. Stick to JDK 8 now, if you want to use NetBeans.

Writing a Hello-world Java Program in NetBeans

Step 0: Launch NetBeans

Launch NetBeans. If the 'Start Page' appears, close it by clicking the 'cross' button next to the 'Start Page' title.

Step 1: Create a New Project

For each Java application, you need to create a 'project' to keep all the source files, classes and relevant resources.

1. From 'File' menu ⇒ Choose 'New Project...'.
2. The 'Choose Project' diglog pops up ⇒ Under 'Categories', choose 'Java' ⇒ Under 'Projects', choose 'Java Application' ⇒ 'Next'.
3. The 'Name and Location' dialog pops up ⇒ Under 'Project Name', enter 'FirstProject' ⇒ In 'Project Location', select a suitable directory to save your works ⇒ Uncheck 'Use Dedicated Folder for Storing Libraries' ⇒ Uncheck 'Create Main class' ⇒ Finish.

Step 2: Write a Hello-world Java Program

1. Right-click on 'FirstProject' ⇒ New ⇒ Java Class (OR choose the 'File' menu ⇒ 'New File...' ⇒ Categories: 'Java', File Types: 'Java Class' ⇒ 'Next').
2. The 'Name and Location' dialog pops up ⇒ In 'Class Name', enter 'Hello' ⇒ Delete the content in 'Package' if it is not empty ⇒ 'Finish'.
3. The source file 'Hello.java' appears in the editor panel. Enter the following codes:

Step 3: Compile & Execute

There is no need to 'compile' the source code in NetBeans explicitly, as NetBeans performs the so-called incremental compilation (i.e., the source statement is compiled as and when it is entered).

To run the program, right-click anywhere in the source (or from the 'Run' menu) ⇒ Run File. Observe the output on the output console.

Notes:

• You should create a NEW Java project for EACH of your Java application.
• Nonetheless, NetBeans allows you to keep more than one programs in a project, which is handy for writing toy programs (such as your tutorial exercises). To run a particular program, open and right-click on the source file ⇒ Run File.

Correcting Syntax Error

NetBeans performs incremented compilation, as and when a source line is entered. It marked a source line with syntax error with a RED CROSS. Point your cursor at the RED CROSS to view the error message.

You CANNOT RUN the program if there is any syntax error (marked by a RED CROSS before the filename). Correct all the syntax errors; and RUN the program.

[TODO] Diagram

HINTS: In some cases, NetBeans shows a ORANGE LIGHT-BULB (for HINTS) next to the ERROR RED-CROSS (Line 5 in the above diagram). You can click on the LIGHT-BULB to get a list of HINTS to resolve this particular error, which may or may not work!

SYNTAX WARNING: marked by a orange triangular exclaimation sign. Unlike errors, warnings may or may not cause problems. Try to fix these warnings as well. But you can RUN your program with warnings.

Read the NetBeans Documentation

At a minimum, you SHOULD READ the 'IDE Basics, Getting Started, Java Application', which is accessible via NetBeans's 'HELP' menu ⇒ Help Contents. This will save you many agonizing hours trying to figure out how to do somethings later.

The 'Help' ⇒ 'Online Doc and Support' (@ http://netbeans.org/kb/index.html) contains many articles and tutorial on using NetBeans.

The NetBeans 'Start Page' also provides many useful links to get you started.

Debugging Program in NetBeans

Step 0: Write a Java Program

The following program computes and prints the factorial of n (=1*2*3*...*n). The program, however, has a logical error and produce a wrong answer for n=20 ('The Factorial of 20 is -2102132736' - a negative number?!).

Let us use the graphic debugger to debug the program.

Step 1: Set an initial Breakpoint

A breakpoint suspends program execution for you to examine the internal states of the program. Before starting the debugger, you need to set at least one breakpoint to suspend the execution inside the program. Set a breakpoint at main() method by clicking on the left-margin of the line containing main(). A red circle or an inverted Triangle appears in the left-margin indicating a breakpoint is set at that line.

Step 2: Start Debugging

Right click anywhere on the source code ⇒ 'Debug File'. The program begins execution but suspends its operation at the breakpoint, i.e., the main() method.

As illustrated in the following diagram, the highlighted line (also pointed to by a green arrow) indicates the statement to be executed in the next step.

Step 3: Step-Over and Watch the Variables and Outputs

Click the 'Step Over' button (or select 'Step Over' in 'Debug' menu) to single-step thru your program. At each of the step, examine the value of the variables (in the 'Variable' panel) and the outputs produced by your program (in the 'Output' Panel), if any. You can also place your cursor at any variable to inspect the content of the variable.

Single-stepping thru the program and watching the values of internal variables and the outputs produced is the ultimate mean in debugging programs - because it is exactly how the computer runs your program!

Step 4: Breakpoint, Run-To-Cursor, Continue and Finish

As mentioned, a breakpoint suspends program execution and let you examine the internal states of the program. To set a breakpoint on a particular statement, click on the left-margin of that line (or select 'Toggle Breakpoint' from 'Run' menu).

'Continue' resumes the program execution, up to the next breakpoint, or till the end of the program.

'Single-step' thru a loop with a large count is time-consuming. You could set a breakpoint at the statement immediately outside the loop (e.g., Line 11 of the above program), and issue 'Continue' to complete the loop.

Alternatively, you can place the cursor on a particular statement, and issue 'Run-To-Cursor' to resume execution up to the line.

'Finish' ends the debugging session. Always terminate your current debugging session using 'Finish' or 'Continue' till the end of the program.

Other Debugger's Features:

Modify the Value of a Variable

You can modify the value of a variable by entering a new value in the 'Variable' panel. This is handy for temporarily modifying the behaviour of a program, without changing the source code.

Step-Into and Step-Out

To debug a method, you need to use 'Step-Into' to step into the first statement of the method. You could use 'Step-Out' to return back to the caller, anywhere within the method. Alternatively, you could set a breakpoint inside a method.

NetBeans - Tips & Tricks

General Usage

These are the features that I find to be most useful in NetBeans:

1. Maximizing Window (double-click): You can double-click on the 'header' of any panel to maximize that particular panel, and double-click again to restore it back. This is particularly useful for editing source code in full panel.
2. Code Auto-Complete (or Intelli-Sense) (ctrl-space): Enter a partial statement (e.g., Sys) and press control-space to activate the auto-complete, which displays all the available choices.
3. Javadoc (ctrl-space, alt-F1): Place the cursor on a method or class, and press ctrl-space to view the javadoc; or right-click ⇒ Show Javadoc (alt-F1) to open it on a browser.
4. Code Shorthand (tab): For example, you can enter 'sout' and press TAB for 'System.out.println'; 'psvm' for 'public static void main(String[] args) { }' or 'fori' + tab for a for-loop. To view and configure code template, choose 'Tools' menu ⇒ 'Options' ⇒ 'Editor' ⇒ 'Code Templates'.
5. Formatting Source Code (alt-shift-f): Right-click on the source (or from the 'Source' menu) ⇒ Choose 'Format'. NetBeans will layout your source codes with the proper indents and format. To configure the formatting, choose 'Tools' menu ⇒ 'Options' ⇒ 'Editor' ⇒ 'Formatting'.
   You can also select the section of codes to be formatted, instead of the entire file.
6. Hints for Correcting Syntax Error: If there is a syntax error on a statement, a red mark will show up on the left-margin on that statement. You could click on the 'light bulb' to display the error message, and also select from the available hints for correcting that syntax error.
7. Rename (Refactor) (ctrl-r): To rename a variable, place the cursor on that variable, right-click ⇒ 'Refactor' ⇒ 'Rename' ⇒ Enter the new name. All the appearances of that variables in the project will be renamed.
8. Small Programs: You can keep many small toy programs (with main()) in one Java project instead of create a new project for each small program. To run the desired program, on the 'editor' panel ⇒ right-click ⇒ 'Run File'.
9. Source Toggle Comment: To temporarily comment-off a block of codes, choose 'Source' ⇒ 'Toggle Comment'.
10. Error Message Hyperlink: Click on an error message will hyperlink to the corresponding source statement.
11. Command-Line Arguments: To provide command-line arguments to your Java program in NetBeans, right-click on the 'project' ⇒ 'Set as Main Project' ⇒ 'Set Configurations' ⇒ 'Customize...' ⇒ 'Run' ⇒ select the 'Main' class ⇒ type your command-line arguments inside the 'Arguments' field ⇒ choose 'Run' menu ⇒ 'Run Main Project'.
12. Line Numbers: To show the line numbers, right-click on the left-margin ⇒ 'Show Line Numbers'.
13. Changing Font Face and Size: Tools ⇒ Options ⇒ Fonts & Colors ⇒ In 'Category', select 'Default' ⇒ In 'Font', choose the font face and size.
14. Resetting Window View: If you mess up the window view (e.g., you accidentally close a window and cannot find it anymore), you can reset the view via 'Window' menu ⇒ 'Reset Windows'.
15. Code Templates: For example, when you create a new Java class, NetBeans retrieves the initial contents from the 'Java Class' code template. To configure code templates, select 'Tools' menu ⇒ 'Templates' ⇒ Choose the desired template ⇒ 'Open in Editor'. To set a value of a variable used in the all the code templates (e.g., $User), select 'Tools' menu ⇒ 'Templates' ⇒ 'Settings'.
16. Displaying Chinese Character: Need to choose a font that support chinese character display, such as 'Monospace', in Tools ⇒ Options ⇒ Fonts & Colors ⇒ Syntax ⇒ default.
17. Changing the JDK Location: The Netbeans configuration file is located at 'etcnetbeans.conf'. Edit the directive 'netbeans_jdkhome'.
18. Let me know if you have more tips to be included here.

Java Application Development

1. Choosing the JDK version for your program: Right-click on your project ⇒ 'Properties' ⇒ 'Source' node ⇒ You can select the JDK level of your project in pull-donw menu 'Source/Binary Format'.
2. Enabling JDK 7 support: If JDK 7 is already installed in your system, right-click on your Project ⇒ 'Properties' ⇒ 'Source' node ⇒ 'Source/Binary Format' ⇒ Select 'JDK 7'. Also check 'Libraries' ⇒ Java Platform ⇒ JDK 7.
   If JDK 7 is not installed/configured, install JDK 7. Add JDK 7 support to NetBeans via 'Tool' menu ⇒ 'Java Platforms' ⇒ 'Add Platform...'.
3. Choosing Default Charset: Right-click on your project ⇒ 'Properties' ⇒ 'Source' node ⇒ 'Encoding' ⇒ choose your desired charset for the text-file I/O from the pull-down menu.
4. Enabling Unicode Support for File Encoding: Right-click on your project ⇒ 'Properties' ⇒ 'Source' node ⇒ 'Encoding' ⇒ choose your Unicode encoding (e.g., UTF-8, UTF-16, UTF-16LE, UTF-16GE) for the text-file I/O.
5. To include Javadoc/Source: Use 'Library Manager' (select the 'Tools' menu ⇒ 'Libraries'); or 'Java Platform Manager' (select 'Tools' menu ⇒ 'Java Platforms')
6. Adding External JAR files & Native Libraries ('.dll', '.lib', '.a', '.so'): Many external Java packages (such as JOGL, Java3D, JAMA, etc) are available to extend the functions of JDK. These packages typically provide a 'lib' directory containing JAR files ('.jar') (Java Archive - a single-file package of Java classes) and native libraries ('.dll', '.lib' for windows, '.a', '.so' for Linux and Mac).
   To include an external JAR file ('.jar') into a project: Expand the project node ⇒ Right-click on 'Libraries' ⇒ 'Add JAR/Folder...' ⇒ Select the desired JAR file or the folder containing the classes.
   If the external package contains many JAR files, you could create a user library to contain all the JAR files, and add the library to all the projects that required these JAR files. From 'Tools' menu ⇒ 'Libraries' ⇒ 'New Library...' ⇒ Enter a library name ⇒ Use 'Add JAR/Folder...' to add JAR files into this library.
   Many JAR files come with native libraries in the form of '.dll', '.lib' (for Windows) and '.a', '.so' for Linux/Mac. The directory path of these libraries must be included in JRE's property 'java.library.path'. This can be done via right-click the project ⇒ Set Configuration ⇒ Customize... ⇒ Run ⇒ In 'VM options', enter '-Djava.library.path=xxx', where xxx is path of the native libraries.
   Notes: The JAR files must be included in the CLASSPATH. The native library directories must be included in JRE's property 'java.library.path', which normally but not necessarily includes all the paths from the PATH environment variable. Read 'External JAR files and Native Libraries'.

Writing Java GUI (AWT/Swing) Application in NetBeans

Step 0: Read

1. Java GUI Application Learning Trail @ http://www.netbeans.org/kb/trails/matisse.html.
2. Swing Tutorial's 'Learning Swing with the NetBeans IDE' @ http://docs.oracle.com/javase/tutorial/uiswing/learn/index.html.

Step 1: Create a New 'Java Application' Project

1. Launch NetBeans ⇒ File ⇒ New Project...
2. Under 'Categories', choose 'Java' ⇒ Under 'Projects', choose 'Java Application' ⇒ Next.
3. In 'Project Name', enter 'FirstNetBeansGUI' ⇒ Choose a suitable directory for your 'Project Location' ⇒ Uncheck the 'Create Main class' box ⇒ Finish.

Step 2: Write a Java File 'JFrame Form'

1. Right-click on the project 'FirstNetBeansGUI' ⇒ 'New' ⇒ 'JFrame Form...' (or 'Others' ⇒ 'Swing GUI Forms' ⇒ 'JFrame Form').
2. In 'Class Name', enter 'NetBeansSwingCounter' ⇒ Finish.
3. Create the GUI Components visually:
   1. From the 'Platte' panel ⇒ 'Swing Controls' ⇒ Drag and drop a 'Label', 'TextField', and 'Button' into the design panel.
   2. Click on the 'jLabel1' ⇒ In the 'Properties' panel, enter 'Count' in 'text' (You can also single-click on the jLabel1 to change the text). Right-click on the jLable1 ⇒ Change Variable Name ⇒ In 'New Name', enter 'lblCount'.
   3. Similarly, for 'jTextField1' ⇒ Change the 'text' to 0, and change the 'Variable Name' to 'tfCount' ⇒ Resize the text field if necessary.
   4. For 'jButton1' ⇒ Change the 'text' to 'Count', and change the 'Variable Name' to 'btnCount'.
4. Write the event handler for the button by double-clicking the button and enter the following codes:
5. Create an instance variable count (just below the class declaration) as follows:

Step 3: Compile & Execute

Right-click the source and select 'Run File'.

Step 4: Study the Generated Source Code

Expand the 'Generated Code' and study how the GUI builder declare, allocate and initialize the GUI Components in the initComponents(). Note how the JButton registers an ActionEvent listener and how an inner class is used as the listener and provide the event handler actionPerformed(). Also notice that the main() method uses a Swing's worker to run the GUI on the Event-Dispatcher thread, instead of the main thread, for thread-safe operations.

NetBeans and MySQL

Reference: 'Connecting to a MySQL Database' @ http://netbeans.org/kb/docs/ide/mysql.html.

What To Do After You Download Java Jdk On Mac Catalina

Generating a WAR-file for a Web Application

A WAR (Web Archive) file is basically a zip file for distributing web application in single file. You can use WinZip or WinRAR to inspect or unzip the war file.

To distribute the project as a war-file, right-click project ⇒ 'Clean and Build'. The war file is created in the 'dist' directory. You can deploy the web application by dropping the war-file into Tomcat's 'webapps' directory. Tomcat will automatically unzip the war-file and deploy the application upon startup.

Debugging Web Application

The most important reason for using IDE is to use the graphic debugger for debugging the program. You can set a breakpoint in your server-side Java codes, and 'Debug' a web application, similar to a standalone application.

REFERENCES & RESOURCES

• NetBeans mother site @ http://netbeans.org.
• NetBeans 'Help' menu.

You may want to print these instructions before proceeding.You should read each step completely before performing the action it describes.Because these products may change slightly each semester, I would appreciate it if you would let me know if you find any discrepancies between these instructions and what actually happens when you try to follow them.

IMPORTANT: Install Java first, BEFORE you install Eclipse.

Java

The following instructions were composed for installing Sun Java 1.5.0_08 (aka JDK 5.0 update 8).This may not be the latest version, but it is the one that we are using this semester.Note: Java is already installed as part of Mac OS X, so no further installation is necessary for these machines.Ensure, though, that you have the right version by typing java -version to the unix command prompt;the response should be something like java version '1.5.0_08'

A typical Java installation takes about 400 megabytes of disk space.The installation process reports the exact size.

Downloading

1. Click Java SE Downloads
   A page, with this label in orange, will be displayed in your browser.
2. Find the section labeled JDK 5.0 Update 8 and click its Download button (the fourth one from the top). Click Yes to the Security Window pop-up, if it appears. A page, with the label Download in orange, will be displayed in your browser.
3. Click the Accept button, which appears under Required in red (it is in a small font: look for it carefully).
   Again, click Yes to the Security Window pop-up, if it appears. This page will re-display itself, with this information absent.
4. Find the black bar labeled Windows Platform - J2SE(TM) Development Kit 5.0 Update 8
5. Click the link labeled Windows Online Installation (typical download size is ~33.7MB), Multi-language
6. Save the file it is about to download somewhere on your disk drive. The file will be named jdk-1_5_0_08-windows-i586-p-iftw.exe. The exact form of this interaction will depend on the version of your operating system (on mine clicked Save to the File Download - Security Warning pop-up; then I specified the location for the file; and then I clicked Close to the Download complete pop-up). Store this exe file somewhere permanent on your disk drive, so that you can reexecute it (reinstall Java) later, if necessary. This file is only about 250KB (1/4 MB).
7. Terminate (X) any windows remaining from this process (e.g., the Download window).

Installing

1. Double-click the file that you just downloaded, to run it.
   Click Run to the Open File - Security Warning pop-up. You will see a Windows Installer window temporarily then a Preparing to Install window temporarily. You will then see a License Agreement window.

What To Do After You Download Java Jdk On Mac Os

Eclipse

The following instructions were composed for installing Eclipse 3.2 on Windows.The process for Mac/Linux should be similar.If later versions of Eclipse come out before I update these instructions, you might have to go through a slightly different process (please contact me if you do).

What To Do After You Download Java Jdk On Mac High Sierra

A typical installation takes about 134 Mb of disk space (plus the 120 Mb download, which you should keep on your machine, in case you need to reinstall it).

Downloading

1. Click Eclipse 3.2
   A page, with the label eclipse downloads, will be displayed in your browser.
2. In the first section, find the text Download Now: Eclipse SDK 3.2, Windows (120 MB)
3. Click the icon to the left of this text, or the part of the text labeled Eclipse SDK 3.2
   If you are using a Mac, it should sense it and display Mac instead of Windows. If you are not using the operating system it recognizes, click the link labeled Other downloads for 3.2 instead.
4. Click the icon to the left of the text Download from: for using the default mirror site (or click a site from the list displayed in the box).
5. Click the Save button to download, somewhere on your disk, the file named eclipse-SDK-3.2-win32.zip (for PCs). The exact form of this interaction will depend on the version of your operating system. Store this zip file somewhere permanent on your disk drive, so that you can unzip it (recreate Eclipse) later, if necessary
6. Terminate (X) any windows remaining from this process.

Installing

1. Unzip this file that you just downloaded.
   On most Windows machines, you can
   • Right-click the file.
   • Move to the WinZip command.
   • Click Extract to here
   It creates a folder named eclipse. You can leave this folder here or move it elsewhere on your disk drive.
2. Create a shortcut on your desktop to the eclipse.exe file.
   On most Windows machines, you can
   • Right-press the file eclipse.exe
   • Drag it to the desktop.
   • Release the right button.
   • Click Create shortcut here
   Now you are ready to perform a one-time only setup of Eclipse.
3. Double-click the shortcut to Eclipse that you just created. In the Workspace Launcher window, in the box following Workspace:, should appear something like C:Documents and Settingsusernameworkspace (where username is your login on the machine). If you want, you can type in (or browse) another location for the workspace file to be created, but I advise accepting the default.
4. Check the box labeled Use this as the default and do not ask again.
   Aside: you will be using one workspace during the semester, checking projects in and out of this workspace. If you ever want to re-enable the display of this window, once Eclipse starts, you can
   • Select Window | Preferences.
   • Click the + in front of General or double-click General (after the +)
   • Click Startup and Shutdown
   • Check the box labeled Prompt for workspace on startup.
5. Click OK
6. If you want easy access to the workspace, create a shortcut to it (see the instructions above), putting the shortcut on your desktop.
7. Download (right-click and Save As) Course Library Jar into the same folder that you are using as your workspace (or move this file in the workspace fodler after downloading it elsewhere).
8. In Eclipse, select Windows | Preferences
9. Click the + in front of Java or double-click Java (after the +)
10. Click Installed JREs
11. Under the Name column, double-click jre1.5.0_08.
12. Click the Add External Jars... button.
13. In the Jar Selection window, navigate to your workspace folder, and double-click the file cs15-1xx.library.
14. In the Edit JRE window, click OK
15. In the Installed JREs window, click OK
16. Terminate (X) the Welcome window
    You can always get it back by selecting Help | Welcome
17. Terminate (X) the Eclipse window.
