Everything in Java is associated with classes and objects, along with its attributes and methods. For example: in real life, a car is an object. The car has attributes, such as weight and color, and methods, such as drive and brake. A Class is like an object constructor, or a “blueprint” for creating objects .

Let’s enlarge the basic program from Tutorial 1 to actually create a new object from the class we define. This program outputs nothing . Like our previous programs, it defines a class (called “Animal”).
Read moreWhat is an example of polymorphism in Java?
Polymorphism is one of the OOPs feature that allows us to perform a single action in different ways. For example, lets say we have a class Animal that has a method sound() . Since this is a generic class so we can’t give it a implementation like: Roar, Meow, Oink etc.

Example 1: Java Inheritance eat(); Here, labrador is an object of Dog . However, name and eat() are the members of the Animal class. Since Dog inherits the field and method from Animal , we are able to access the field and method using the object of the Dog .
