What is Interface in java? Explain use of Interface with the help of a Java program

In Java, an interface is a collection of abstract methods that define a contract or a set of behaviors that a class must implement. It provides a way to achieve abstraction and define common functionality that can be shared across different classes. Here are some key points about interfaces in Java:

1. Interface Declaration: An interface is declared using the interface keyword, followed by the interface name. It defines the methods that the implementing classes must implement.

2. Abstract Methods: Interfaces consist of abstract methods, which are methods without an implementation. They only declare the method signature, return type, and parameter list. Interfaces can also include constant fields, which are implicitly public, static, and final.

3. Multiple Inheritance: Unlike classes, Java allows a class to implement multiple interfaces. This enables a ___ ___ ______ _____ ___ _________ _______ __________ _______ ______ ______ ____.
