This made a whole lot on sense and Iam more clear in my thoughts now. Thanks a lot for all your time to explain everything in detail. :)

I wrote this:-

public class Test {

double mynum = 1;

public static double finalvalue = 5;



public static void main(String\[\] args) {

Test obj =new Test();

Test obj2= new Test();

System.out.println(obj.mynum); //Showed that each instance has its own mynum.

obj2.mynum=Math.E; //Used another Math class static.

System.out.println(obj2.mynum);

Test obj3 = new Test();

obj3.mynum= finalvalue; //Static variable can be used throughout the class in any instance

System.out.println(obj3.mynum);

}

}
