Thanx everybody i got it
jvm is outside the class . it can call public main() method.it is right.but what if class is in default access and public main is there.then also it is able to call it.
I just want to ask how JVM enters a non-public class?
Why main() method must be public so that it be called from JVM?
why class name may not be public in which main method is there cause ?JVM is outside the class>...........
