Abstract Class:
(1)it contains both abstract methods and non abstract methods
(2) object can't be created just through reference we are calling all the methods
(3) it is implemented by subclass i.e which class is extended from this
abstract class contains only nonabstract this situation also code will compile fine but problem at runtime
abstract can't be declared with Final Synchronized Native just your requirements you implement some methods in the abstract class
this class also contain Constructor

========
Interface contains all abstract methods
all methods compulsory implemented by particular class
interface does not contain Constructor
