This will do the job: java -classpath yourjar.jar youpackage.B

Why don't you create a Main class that accepts an argument? That argument will decide whether to execute Class A or Class B then.

This is already supported directly by the java command, no reason to write custom code to do the same thing. – Tony Apr 10 '17 at 17:22

Use a command-line switch to identify whether Class A or Class B should be executed.
