What Is Object :

In this page, we will learn about Java objects and classes. In object oriented programming technique, we design a program using objects and classes. An object in Java is the physical as well as logical entity whereas a class

Defination Object :

An object is an instance of a class. A class is a template or blueprint from which objects are created. So, an object is the instance(result) of a class. An entity that has state and behavior is known as an object e.g. chair, bike, marker, pen, table, car etc. It can be physical or logical (tangible and intangible). The example of an intangible object is the banking system.

An object has three characteristics: 

1.State: represents the data (value) of an object.

2.Behavior: represents the behavior (functionality) of an object such as deposit, withdraw, etc.

3.Identity: An object identity is typically implemented via a unique ID. The value of the ID is not visible to the external user. However, it is used internally by the JVM to identify each object uniquely.
