1. First of all in one java file you can not have two public classes.

2. Second you will have to run a particular public class "java classname" and then its main method would run.

Note - If there is no main, you would create object of that class or make it static to access its methods. Another thing is what we call as reflection. One more is overriding where JVM will call that method.
