It is because you have not properly set path for java or you are using wrong version of java.

Solution (for windows):

Check the version of your jdk and jre executing following commands in command prompt:

javac -version

java -version

If any of this is showing no version or an old version set the path in environment variable ( set in both System and User variables).

Make sure you are using the latest version of java.

It will fix the problem,

Happy Coding!!
