Hi Depak,
I assume you meant to say: doubt about binding. The concept relates to polymorphism.
Static (Early) Binding:
Traditional method of compiler determining the exact method to call. The binding depends on the object variable alone.
Dynamic (Late) Binding:
Object oriented approach to determining the method to call at run-time. The compiler places code so that the run-time environment will be able to determine the exact method to call. The binding depends on the type of the object.

Early binding:
Compiler does this binding..
(eg.,)
class variables, Static methods, static Variables ar involved in this.
Late Binding:
Done by JVM
(eg.,)
instance methods mainly, and determining class of a particular operation at run time
