Use of Public-----There is always only one main class that
is one file having only one main file. Since that main file
is used anywhere means might be in another package so there
is a public use of keyword that is public keyword is
required for main function

Static:-----Since compiler in java always look the main
function and when compiler always calls the main so main
class is loaded in first time call for that static keyword
is used.
you can use
1)public void main(String args[])
it compiles file but wont run\

2) void main(String args[])
it compiles file but wont run

3)void main(String args[])
it compiles file but wont run
