What is public what is static what is void ..... Why do we need this ... Without them why cant we run program .... What they do

Question

if u give examples instead of hard definations ... so i can understand perfectly ...

Answer 1

Public and private are basically saying this method or function can or cannot be globally accessed.

Answer 2

Public static void main method is witten in Jvm class.
When we try to run program Jvm first search whether this main method is present or not. If present then it start execution otherwise we will get runtime error
Public: to call by jvm from anywhere

Static: without existing object jvm has to call this method and main method. No way related to any object

Void: main method wont return anything to jvm

Main : this is the name which is configured inside jvm

Hope this will help you
