How to access a non static method in an abstract class's static method?

Why is the main method in Java public?

• What is its use if the class containing the main method is itself default (no access specifier)? How JVM is able to access a main method in a default class? If in any class a method is public and the class containing that method is itself default(i.e. no access specifier) then we know that method can not be accessed by any class outside the package. So how JVM is able to execute main method when we write it into a non public or default class?

• Answer:

  http://docs.oracle.com/javase/specs/jls/se7/html/index.html says nothing about the type of the class which contains the main method. However, main method must be public. (See section 12.1 from the specification.) The main method being static, the JVM can call the method without creating an instance of the class containing it. Hence the class being non-public does not make a difference as far as the entry point of JVM is concerned.
