Interfaces are widely used as central design elements of Java applications. Although interfaces are abstract types similar to abstract classes, the usage of interfaces in Java applications may considerably differ from the usage of abstract classes. Unlike abstract classes, interfaces are meant to enable multiple inheritance.
Thus we can say that subclass are specialized version of superclass. Benefits of Java's Inheritance. 1. Reusability of code. 2. Code Sharing. 3. Consistency in using an interface. Classes. Superclass(Base Class). Subclass(Child Class). It is a class from which other classes can be derived. It is a class that inherits some or all.

Software engineering has been using interfaces for over 25 years. Java, in contrast to other object-oriented programming languages like C++ and Smalltalk, provides a clean separation between interfaces and classes that implement the interfaces. For new Java developers, this requires some adjustment in thinking.
Represents a list of integers. public interface IntList { public void add(int value); public void add(int index, int value); public int get(int index); public int indexOf(int value); public boolean isEmpty(); public void remove(int index); public void set(int index, int value); public int size();. } public class ArrayIntList implements IntList { .
Interface in Java: Interface is used for achieving full abstraction in java. An interface is like a template that we can use in our classes..
A class can implement more than one interface (the Java platform supports multiple inheritance for interfaces), so the implements keyword is followed by a comma-separated list of the interfaces implemented by the class. When implement an interface, either the class must implement all the methods declared in the interface
6 Apr 2016 understanding and designing modern software recognizes: – Modern software consists of potentially large numbers of components that are composed into “larger" components/systems. – In Java, one ordinarily thinks of a class as a component, with its client-visible specification in the interface(s) it
6.170 Lecture 15. Fall 2005. Classes and interfaces lie at the heart of the Java programming language. In this lecture, we describe guidelines to help you design classes and interfaces that are usable, robust and flexible. This lecture draws from the material in Chapter 4 of Joshua Bloch's book, Effective Java. Accessibility.
JAVA - INTERFACES. An interface is a reference type in Java, it is similar to class, it is a collection of abstract methods. A class implements an interface, thereby inheriting the abstract methods of the interface. Along with abstract methods an interface may also contain constants, default methods, static methods, and nested
