what is the diffarence between interface and abstract class ?
1)An abstract class may contain complete or incomplete methods while Interfaces can contain only the signature of a method but no body.
2)An abstract class cannot support multiple inheritance, while an interface can support multiple inheritance.
3)One class can inherit multiple interface but it can't inherit multiple abstract class
