Java Object

 
Object is the basic entity of object oriented programming language. Object is the feature of a class, which is used for the working on the particular properties of the class or its group. Java object is an instance of the class. It takes the properties (variables) and uses the behavior (methods) defined in the class. In Java, when you define a class that does not extend any other class, it implicitly extends java.lang.Object class, which is a super class of all the classes of Java.
