Answer Posted / prashant sharma
1.Interface myInterface{....};
2.Class myClass{......}
3.myInterface vInterace;
4.vInterface = new myClass();
In line 3 we are creating a var of type myInterface. It
holds an memory space for var type myInterface. it is just
like any other var type. Why there can't be ann object of
interface ..ans to this lies in post 1
In line 4 we create a object of class myClass. This object
returns the reference of space hold by class object on heap.
Thanks to JAVA inheritence structure, now variable
vInterface can refer to object of myClass as they are
interrelated
Interrelated in the sense taht when a class implements an
interface its object create definition of the interface in
the object on heap.
Hope it helps....
