How different are interface and abstract class in ...
when a class is not provided with full functionalitythen it is declared as abstract.it doesn't support instance creation as well as it cannot be overridable to child class.interface is a colection of methods only without functionality.interface is 90 same as abstract class.
RE: How different are interface and abstract class in ...
1. Abstract class can have method with implementation interface can only have method definitions 2. You can inherit multiple interface but cannot inherit multiple abstract class
