Difference between abstract class and an interface. code example

Example 1: difference between abstract and interface

Interface 
1) Interface contains only abstract methods 
2) Access Specifiers for methods in interface
must be public
3) Variables defined must be public , static ,
final
4) Multiple Inheritance in java is implemented
using interface
5) To implement an interface we use
implements keyword

Abstract Class
1) Abstract class can contain abstract methods,
concrete methods or both
2) Except private we can have any access
specifier for methods in abstract class.
3) Except private variables can have any access
specifiers
4)We cannot achieve multiple inheritance using
abstract class.
5)To implement an interface we use implements
keyword

Example 2: abstract classes vs interfaces

Interface 
1) Interface contains only abstract methods 
2) Access Specifiers for methods in interface
must be public
3) Variables defined must be public , static ,

2) Except private we can have any access
specifier for methods in abstract class.
3) Except private variables can have any access
specifiers
4)We cannot achieve multiple inheritance using

5)To implement an interface we use extends
keyword
