Java Environment Setup tutorials

  • This topic will guide you about how to download Java Development Kit(JDK) and set up Java in your machine for creating, compiling, debugging and running Java code.

  • You can download JDK SE from the link Download Java and choice a version based on your operating system.

  • After downloading JDK run the .exe to install Java on your machine, this JDK also provide a private Java Runtime Environment(JRE) which is necessary for running the Java code.

  • Once you installed Java on your machine, you would need to set environment variables to point to correct installation directories:

Setting up the path for windows Vista/ 7 or 8

  • Assuming you have installed Java in c:\Program Files\java\jdk directory:

  • Right-click on ‘Computer’ and select ‘Properties’

  • Click on ‘Advanced System Settings’ tab

  • Click on ‘Environment variables’ button at the bottom of the window.

  • Click on the path and select ‘Edit’ option.

  • Now add the java path to the path variable. Append c:\Program Files\java\jdk\bin to it.

Setting up the path for windows 2000/XP

  • Assuming you have installed Java in c:\Program Files\java\jdk directory:

  • Right-click on ‘My Computer’ and select ‘Properties’

  • Click on the ‘Environment variables’ button under the ‘Advanced’ tab

  • Now alter the ‘Path’ variable so that it also contains the path to the Java executable. Example, if the path is currently set to ‘C:\WINDOWS\system32’,

  • Now append c:\Program Files\java\jdk\binto path variable.

Setting up the path for Linux, UNIX, Solaris, FreeBSD

  • Environment variable PATH should be set to point to where the java binaries have been installed. Refer to your shell documentation if you have trouble doing this.

  • Example, if you use bash as your shell, then you would add the following line to the end of your ‘.bashrc: export PATH=/path/to/java:$PATH’

Popular Java Editors

  • For writing the Java programs code you will need a text editor. You can use Operating Systems vender supplied text editor such as Notepad or WordPad for Windows based machine or VI editor for Linux based machine. But there are even more sophisticated and flexible Integrated Development Environment (IDE) is available in the market for developing any Java program.

  • An IDE is an Integrated Development Environment which is a software application that provides comprehensive facilities to computer programmers for software development. An IDE normally consists of a source codeeditor,

  • build automation tools and adebugger. Several modern IDEs integrate with Intelli-sensecoding features.

  • Below is some of the editors mostly use for Java development.

    • Notepad: Notepad is a very simple text editor where you can write a Java code, for the beginners who want to learn Java Notepad editor is recommended.

    • Netbeans: Netbeans is a Java IDE that is open source and free which can be downloaded from http://www.netbeans.org/. In this IDE you can create any Java technology program.
