What is abstract class interface in Java?
Abstract Class Vs.
Interface: Explore the Difference between Abstract Class and Interface in Java.
The Abstract class and Interface both are used to have abstraction.
An abstract class contains an abstract keyword on the declaration whereas an Interface is a sketch that is used to implement a class.What is abstract method in Java?
Abstract methods are those types of methods that don't require implementation for its declaration.
These methods don't have a body which means no implementation.
A few properties of an abstract method are: An abstract method in Java is declared through the keyword “abstract”.What is abstraction in object-oriented programming javatpoint?
Abstraction is the process of hiding the details of an entity and focusing on the essential characteristics of the entity.
In object-oriented programming, abstraction is an important concept that helps developers to model real-world entities in the code.Abstraction in Java can be achieved in two ways:
Abstraction in Java can be achieved in two ways:
1Using abstract classes.
Abstract classes achieve partial abstraction as concrete methods can also be defined in them.
2) Using interfaces.
Interfaces achieve complete abstraction as only abstract methods can be defined in them.
- Abstract class can have abstract and non-abstract methods.
- Abstract class doesn't support multiple inheritance.
- Abstract class can have final, non-final, static and non-static variables.
- Abstract class can provide the implementation of interface.
