What is the use of Main Method in Java programming Language

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!
