About Final Object

Question

Its possible to change the state of a final object .
What is the idea behind this .. ?
I am disturbed by this fact ..can any one tell me why?
public class FinalTest
     public static void main(String args[])
          final MyFinal a = new MyFinal();
          a.x=1;
          a.y=1;
          a.callMethod();
          a.show();
class MyFinal
     public int x = 0 ;
     public int y = 0 ;
     public void callMethod()
          x*=2;
          y*=2;
     public void show()
          System.out.println("x:= "+x+" y:= "+y);
}

Thanks for the clarifcation.
Here is the summary..
//FINAL OBJECTS STATE CAN BE MODIFIED.There's no such thing as a final object.
//ITS WRONG TO SAY "FINAL OBJECT" BUT "FINAL OBJECT
REFERENCE" IS THE RIGHT WORD.I'd say "final variable" is more correct, but at least "final reference" makes the crucial distinction between the object and the reference variable that points to it.
//THE CONCEPT OF FINAL EXISTS FOR VARIABLES NOT FOR
OBJECTS.Correct.
