How static keyword works in Java

Use   of   static   keyword .

-------------------------------------

Discussion  on static  keyword .   Here  is one of the  advantage uses  of the static keyword.

class  staticword{

static{

System.out.println("static block is invoked");  }

public static void main(String args[]){

System.exit(0);

System.out.println("Hello");

}

}

Output : -   static  block is invoked

class  statictest{

static{System.out.println("static block is invoked");

}

public static void main(String args[])

{

System.out.println("Hello main");

}

}

output --

Output:static block is invoked

Hello main

static block executes  first  before main.

This   program   will   explain  little bit   how   static   works .

class   stat

{

static  {

System.out.println("Hello first");

//printmethod2();  stat.java:8: error: non-static method printmethod2() cannot be referenced from a static context

}

public  static void main (String args[]){

printmethod();

System.out.println("Hello");

}

public static void printmethod(){

System.out.println("Hello Second");

}

public void printmethod2(){

System.out.println("Non Stat Mehtod");

}

}

Out put   of this  program  is  ..

Look  at  sequence  of the exceution

Hello first

Hello Second

Hello
