Updating the PATH Environment Variable
If you do not set the PATH variable, you need to specify the full path to the executable file every time you run it.
It is useful to set the PATH variable permanently so it will persist after rebooting.
To set the PATH variable permanently, add the full path of the JDK directory to the PATH variable. Set the PATH variable as follows on Microsoft Windows:
- Click Start, then Control Panel, then System.
- Click Advanced, then Environment Variables.
- Add the location of the bin folder of the JDK installation to the PATH variable in System Variables.
