Hi All,

About interface,

interface method do not have body .so, it supports multiple inheritence.

well,but my doubt is without body definition,what is the use of implementing the interface.. :roll:

what i feel , Abstract class is meaningful compare to interface

Abstract Classes vs. Interfaces
It may also be instructive to look at real-life implementations, for example, the Java Collections Framework, which makes good use of both interfaces and abstract classes.
