How to set path in Java

The path is required to be set for using tools such as javac, java etc.

If you are saving the java source file inside the jdk/bin directory, path is not required to be set because all the tools will be available in the current directory.

But If you are having your java file outside the jdk/bin folder, it is necessary to set path of JDK.

There are 2 ways to set java path:

  1. Temporary
  2. Permanent

1) How to set Temporary Path of JDK in Windows

To set the temporary path of JDK, you need to follow following steps:

  • Open command prompt
  • Copy the path of jdk/bin directory
  • Write in command prompt: set path=copied_path

Example:

set path=C:Program FilesJavajdk1.6.0_23bin

2) How to set Permanent Path of JDK in Windows

For setting the permanent path of JDK, you need to follow these steps:

    • Go to MyComputer properties -> advanced tab -> environment variables -> new tab of user variable -> write path in variable name -> write path of bin folder in variable value -> ok -> ok -> ok.

Example:

    1. Go to Start Menu > Right Click on Computer > Click Properties.java path

    3. Click on Environment Variables.Environment Variables
