when we run java program, jvm internally calls "main" method.
jvm is built in such a way that it searches for the entire
signature of "main" method i.e public static void
main(String a[])

Example program :
----------------------
class Demo
{
public static void main(String a[])
{ }
}

String a[] -> is used to pass values at runtime.
(c:/>java Demo hai)

public -> providing accessibility for outside code (jvm).

static -> without creating an object calling "main" method
with the class name

c:/>javac Demo.java
c:/>java Demo
(here java internally calls jvm and passes class name
Demo, then jvm loads Demo class and calls Demo.main()
without creating object )

void -> does not return any value because jvm simply calls
main() method and does not have a variable to assign return
value.
