Question

What is the use of Main Method in Java programming Language

Answer 1

As per JLS (Java Language Specification), "A Java virtual machine starts execution by invoking the main() method of some specified class, passing it a single argument, which is an array of strings".

 

Definition of your main method should be as below

 

public static void main(String[] args)

 

public - your method should be accessible from anywhere

 

static - Your method is static, you can start it without creating an instance. When JVM starts, it does not have any instance of the class having main method. So static.

 

void - It does not return anything.

 

Henceforth, the main() method is predefined in JVM to indicate as a starting point.

 

Hope that helps!
