abstract class and interface javatpoint

What is the difference between inheritance vs abstraction in Java?
Inheritance vs Abstraction: A Java interface can be implemented using the keyword “implements” and an abstract class can be extended using the keyword “extends”. Multiple implementations: An interface can extend one or more Java interfaces; an abstract class can extend another Java class and implement multiple Java interfaces.
How to implement an interface in Java?
An interface can be implemented using keyword "implements". Members of a Java interface are public by default. Simply, abstract class achieves partial abstraction (0 to 100%) whereas interface achieves fully abstraction (100%). Let's see a simple example where we are using interface and abstract class both.
What are abstract classes in Java?
Abstract classes are similar to interfaces. You cannot instantiate them, and they may contain a mix of methods declared with or without an implementation. However, with abstract classes, you can declare fields that are not static and final, and define public, protected, and private concrete methods.
What is the difference between abstract class and interface?
But there are many differences between abstract class and interface that are given below. 1) Abstract class can have abstract and non-abstract methods. Interface can have only abstract methods. Since Java 8, it can have default and static methods also. 2) Abstract class doesn't support multiple inheritance. Interface supports multiple inheritance.
