The abstract and Interface even though they are performing same functions are a little bit different.In abstract classes we can give implementation for the methods.In Interface all members we declare are strictly public and also no implementation can be given.so if u have large number of methods which have to be implemented in separate classes u better go for an Interface.on the other hand if u just want to have just simple inheritance from base class u go for abstract class.Remember if u use Interface u cannot declare any contructor inside Interface and all the data members inside Interface are implicitly public final.
please reply if u are clarified
