interface in java
An interface is a special kind of class that cannot be instantiated.
The main idea of an interface is declaring functionality. Interfaces help to
abstract from specific classes and emphasize the functionality.
It makes software design more reusable and clean
Opposite to a class, an interface can extend several interfaces.
A class can implement multiple interfaces.java define interface
/* File name : Animal.java */
interface Animal {
public void eat();
public void travel();
