java main() method is in which class?

[Paul Sturrock]

It is in whichever class you put it in

A Java application needs a main method to start. This is the interface the Java runtime uses to call into your code.

[Piyush Porwal]

or what he means to say is: if you fire "java ClassName", ClassName should have this.

Thank you Paul. I thought, main() is necessary to run the program, so it must me somewhere mentioned in bulit-in classes

No, none of the built-in classes has a main method, because none of the built-in classes is designed as the starting point for an application. You write a class which starts off your application, and you write a main method for the JVM to start with.
