1) abstract classes may contain one or more abstract methods(methods that can't be instantiated). on the other hand interface should contain only abstract methods.
2) abstract classes may implement some of its methods that are not abstract. but interface can't implement any of its method becoz al its methods are abstract.
3)in interfaces all the methods are implicitly abstract,final,static so these modifiers can b omitted but this nit the case wid abstract classes.
4)an important point to note about abstract classes is: they can be subclassed,this sub class implement all the abstract methods that are declared in abstract class.
interfaces provide an alternative to multiple inheritance becoz a class can implement more than one interface.
but an abstract can b sub classed only once.
