Java technology is widely used currently. Let's start learning of java from basic questions like what is java, where it is used, what type of applications are created in java and why use java? What is Java? Java is a programming language and a platform.

Constructor is a special type of method that is used to initialize the object. Constructor is invoked at the time of object creation. It constructs the values i.e. provides data for the object that is why it is known as constructor. Rules for creating constructor There are basically two rules defined for the constructor.

In this page, we will learn about the objects and classes. In object-oriented programming, we design a program using objects and classes. Object is the physical entity whereas class is the logical entity. A class works as a template from which we create the objects.

Inheritance is a mechanism in which one object acquires all the properties and behaviours of parent object. The idea behind inheritance is that you can create new classes that are built upon existing classes. When you inherit from an existing class, you reuse (or inherit) methods and fields, and you add new methods and fields to adapt your new class to new situations.
