can any one explain me how interfaces provides encapsulation
my miss says me :
when you write some thing like

Shape s = new Triangle();  

// where Shape is an interface , it actually provides encapsulation because user can only see that s is of type Shape and not which object is getting created .

totally i didnt get that at all

Interface don't provide encapsulation. They can provide flexibility and information-hiding.

Interfaces are also Java's way of dealing with the issues surrounding multiple-inheritance, such as those experienced by C++ (i.e. the "diamond" problem").
