Accessing main() in public static void main(String arg[])

Question

Can a main() be accessed directly from outside the class in which it is defined? Like for example:

class B { main(); } class A { public static void main(String arg[]) { int a=10; int b=20; System.out.println(a+" "+b); } }

Let's assume that the code could actually compile, in order to call main from class B, you would need an instance of B, something like B b = new B();, then you can use b to call main, something like b.main(); — MadProgrammer

@MadProgrammer Yes. I could do that but as main() has a public modifier and is in class A, I thought of if it could only be directly accessed from within the same class or also from outside the class. — BIJAY

You wouldn't need an instance of class A to call A.main because main is a static method. — David Choweller

@BIJAY I'm probably misinterpreting the question, you might like to clarify it more — MadProgrammer

You can call main method from other class as well because its static.no object reference is require to call static method, but you should call it from other method like below.

public class B { public static void main(String[] args) { String[] s = {"a"}; A.main(s); } } class A { public static void main(String arg[]) { int a=10; int b=20; System.out.println(a+" "+b); } }
