Features | Interface | Abstract Class |
Inheritance | A class may inherit several interfaces. | A class may inherit only one abstract class. |
Code | An interface contains only signature but no code | An abstract class can contain complete, default code and/or just signature that have to be overridden. |
Access Modifiers | An interface cannot have access modifiers | An abstract class can contain access modifiers |
Defines | Interfaces are used to define the peripheral abilities of a class | Abstract class defines the core identity of a class and there it is used for objects of the same type. |
Homogeneity | If various implementations only share method signatures then it is better to use Interfaces. | If various implementations are of the same kind and use common behaviour or status then abstract class is better to use. |
Fields | No fields can be defined | Fields can be defined |
