WHAT IS interface in Java with simple example?

WHAT IS interface in Java with simple example?

The interface in Java is a mechanism to achieve abstraction. There can be only abstract methods in the Java interface, not method body. It is used to achieve abstraction and multiple inheritance in Java. In other words, you can say that interfaces can have abstract methods and variables.

WHAT IS interface in Java for beginners?

An interface in Java is similar to a class, but the body of an interface can include only abstract methods and final fields (constants). A class implements an interface by providing code for each method declared by the interface. All the methods in an interface are assumed public and abstract.

What is interface give an example program?

An interface is a programming structure/syntax that allows the computer to enforce certain properties on an object (class). For example, say we have a car class and a scooter class and a truck class.

What is the purpose of Java interface?

Why do we use interface ? It is used to achieve total abstraction. Since java does not support multiple inheritance in case of class, but by using interface it can achieve multiple inheritance . It is also used to achieve loose coupling.

What are interfaces used for?

Interfaces are useful for the following: Capturing similarities among unrelated classes without artificially forcing a class relationship. Declaring methods that one or more classes are expected to implement. Revealing an object’s programming interface without revealing its class.
