How to set path in Java

  • PATH is a system variable that the operating system uses to find the required executable file from the command line or terminal window.
  • You can configure the PATH system variable using the System utility in Windows Control Panel or in the Linux and Solaris shell startup files.

If you save your Java source files inside the JDK / bin directory, you don’t need to set the path since all the tools are available in the current directory.
However, if you have Java files outside of the JDK / bin folder, you will need to set the path to your JDK.

Setting Java Path in Linux OS

The Linux operating system path settings are the same as the Windows operating system path settings. However, we will use the export tool instead of the settings here. Let’s see how to set the path in the Linux operating system.

export PATH=$PATH:/home/jdk1.6.0.20/bin/
