Difference between Interface and Abstract Class

Compare Interface with Abstract Class

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
