@Pankaj:
What are you trying to do?, trying to call a function from
primitive type/reference, that that will never work. You can
call function on Object types.

Double d = 5.5D; //D is optional as by default it is treated
to be double value
String s = d.toString();

If one tries to do something like
String s = 5.5;
A type mismatch errors will be shown during compilation itself!!
