Installation of JDK and NetBeans

Installing the JDK

1. Double-click the Installer, in the JDK 6.0 Custom Installation dialog box, select the feature component you want to install and click the Change button to select the installation path (modified here to C:\Java\jdk1.6.0_21\) or the default installation path. When you are done, next.

2. After the feature component is installed, a dialog box pops up to configure the Java Runtime Environment (JRE). Click the Change button to select the installation path (modified here to C:\Java\jre6\), or the default installation path. When you are finished, next, start installing the JRE.

3. After the installation is complete, in the JDK installation directory there are bin, demo, Lib, JRE and sample subdirectories, the following are the main functions of each subdirectory.

• Bin directory: Store the tools used to develop Java programs, such as compiling instruction Javac, executing instruction Java, etc.
• DB Directory: The resources and cases used to develop the use of embedded database Derby.
• Demo CATALOG: Store Java platform programming cases with source code, including examples using Swing and other Java base classes and the Java Platform Debugger architecture.
• Include directory: a C + + header file that is used to compile local methods.
• JRE directory: holds the Java runtime Environment (JRE).
• LIB Directory: the class library file that holds the development kit.
• Sample directory: Store The example program that comes with the development kit.
• Src.zip: The source code file that holds the Java class library.

setting up the Java runtime environment

Windows looks for a command based on the PATH environment variable, and the value of path is a series of paths. So after you install the JDK, you also set the environment variables for Windows.

1. Environment variables, properties, System Properties, my computer. Click New in the System Variables Options group, and in the popup dialog box, enter the variable name java_home and its value C:\Java\jdk1.6.0_21 (here for this value, the JDK's installation path), OK.

2. In the System Variables option group, in the path variable, edit, at the beginning, add:%java_home%\bin. Are you sure.

3. Start, run cmd, enter java-version to see the JDK related version of the information, the configuration is successful.

2. Choose the installation path for the NetBeans IDE and the path to the JDK for the NetBeans IDE.

3. All the way to the next installation.
