Static Method:

     1)  Static methods are recommended to perform one time operations such as opening 

           file in read mode or write mode, obtaining data base connection etc…

     2)  Static methods are meant for performing common operations.

     3)  Programmatically static methods are preceded by static keyword.

   Syntax:

    

        Static return-type method-name(number of parameters)

      {

           ------------------  //Block of statements

         ------------------  // Block of statements

       }

    4)  Each and every static method must be accessed w.r.t classname.

     Classname.staticmethodname();

      The following program illustrate the concept of Static data member:

      
        Class staticDemo

       {

          static int x=10;

          static void fun1()

        {

           System.out.println(“this is static function”);

         }

       }

       Class oneclass

     {

        void   fun2();

       {

         staticDemo.fun1();

        System.out.println(“The value of x”+staticDemo.x);// calling static data member using  
                                                                                           //class name

       }

         public static void main(String args[])

       {

           oneclass obj=new oneclass();

           obj.fun2();

       }

     }
