In this example, let say the name of your file is something.java opemipo olagoke first, you need to compile java using javac command and not java: javac something.java After that, a new file will be created: something.class Then you can run this command: java something

Could you please remove the URL in the question tags? Just put 'Java' in tags. FYI URLs are inaccessible in tags.
