Static Concepts in java

Static Definition:

        In classes, a static method is one that is called without an instance of that class(object), while a non-static method is called by instances of the class(object).  

Static Program: 

package static_pack;

public class stat {

      static int i = 12;

      int j = 20;

      static

      {

            subclass sub = new subclass();

            System.out.println("The Static value is: " +i);

            //System.out.println("The Static value is: " +j);

           

            sub.display();

      }

      public static void main(String[] args)

      {

            System.out.println("Oops Main class after static block...");

            subclass.print();

      }

}

create a subclass class in the same package:

package static_pack;

public class subclass

{

      static void print()

      {

            System.out.println("In Subclass static method");

      }

      public void display()

      {

            System.out.println("Static yaar!!");

      }

}

Output:-

The Static value is: 12

Static yaar!!

Oops Main class after static block...

In Subclass static method

Explanation :

                 From the above program u can understand that Static block gets executed before the public static void main(String args[]). The static block gets executed and then the main block gets executed
