NetBeans (@ http://netbeans.org) is an open-source Integrated Development Environment (IDE). NetBeans began in 1996 as a Java IDE student project at Charles University in Prague. Sun Microsystems acquired NetBeans in 1999. In 2010, Oracle acquired Sun (and thus NetBeans).
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.

How to Install NetBeans 8.2How to Install NetBeans on WindowsStep 0: Install JDK
To use NetBeans for Java programming, you need to first install Java Development Kit (JDK). See 'JDK - How to Install'.
Step 1: Download
Download 'NetBeans IDE' installer from http://netbeans.org/downloads/index.html. There are many 'bundles' available. For beginners, choose the 1st entry 'Java SE' (e.g., '
netbeans-8.2-javase-windows.exe ' 95MB).
Step 2: Run the Installer
Run the downloaded installer.
How to Install NetBeans on Mac OS X

To install NetBeans:
You can launch NetBeans from the 'Applications'.
Notes: To uninstall NetBeans, drag the '
/Applications/NetBeans ' folder to trash.
How to Install NetBeans on Ubuntu Linux
To use NetBeans for Java programming, you need to first install JDK. Read 'How to install JDK on Ubuntu'.

Writing a Hello-world Java Program in NetBeansStep 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
Save me fleetwood mac mp3 download. For each Java application, you need to create a 'project' to keep all the source files, classes and relevant resources.
Step 2: Write a Hello-world Java Program
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:
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 NetBeansStep 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 & TricksGeneral Usage
These are the features that I find to be most useful in NetBeans:
Java Application Development
Writing Java GUI (AWT/Swing) Application in NetBeansStep 0: Read
Step 1: Create a New 'Java Application' Project
Step 2: Write a Java File 'JFrame Form'
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
Component s 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.
NetBeans (JavaEE) provides direct support to MySQL server. You can use NetBeans as a GUI client to access a MySQL server, as well as an administrative tool (e.g., starting and stopping the server).
Configuring NetBeans to Support MySQL
From NetBeans 'Window' menu ⇒ Select 'Services'. The 'Services' tab shall appear on the left pane
Database Administration - Start/Stop the Server and Create Databases
Create a new Connection
You need a connection to manipulate data. You can create multiple connections with different users and default databases.
Manipulating Data via a Connection
Create a SQL Script and Run the Script
You can create a SQL script by right-clicking on a project ⇒ New ⇒ 'SQL File'. You can run the script by right-clicking on the SQL script ⇒ 'Run File' ⇒ Select an existing connection (or create a new connection) to run the script. You could also run a single statement (right-click on the statement ⇒ Run Statement) or a selected group of statements (highlight the statements ⇒ Right-click ⇒ Run Selection).
Developing and Deploying Web Application in NetBeansRead:
Web (HTTP) ServersConfiguring Web Server
You could configure the web server via 'Tools' menu ⇒ 'Servers'.

MySQL Database Server
You can also manage the MySQL database server directly from Tomcat. Read 'NetBeans and MySQL' Section.
Writing a Hello-World Servlet/JSP Web ApplicationCreate a New Servlet/JSP Project
Writing a Hello-World JSP
A JSP page called '
index.jsp ' is automatically created, which says 'Hello world!'. To execute this JSP, right-click on the project ⇒ 'Run'. The URL is http://localhost:8080/HelloServletJSP/index.jsp .
Writing a Hello-World Servlet
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.
Writing a Hello-world JSF 2.0 Web ApplicationCreate a New JSF 2.0 Project
Create a new JSF 2.0 Facelet
Writing a Hello-world JSF 1.2 Web ApplicationCreate a New JSF 1.2 Project
Create a new JSF 1.2 Page
Debugging Web Applications in NetBeans
You can debug a webapp just like standalone application. For example, you can set breakpoints, single-step through the programs, etc.
