Java object

What is object in java

It is a basic unit of Object-Oriented Programming and represents real life 
entities. A typical Java program creates many objects, which as you know,
interact by invoking methods. An object consists of : 

State: It is represented by attributes of an object. It also reflects the 
properties of an object.

Behavior: It is represented by methods of an object. It also reflects the 
response of an object with other objects.

Identity: It gives a unique name to an object and enables one object to 
interact with other objects. 

class Student
{ 
    int id;//data member (also instance variable) 
    String name; //data member (also instance variable) 
 
    public static void main(String args[])
    { 
        Student s1=new Student();//creating an object of Student 
        System.out.println(s1.id); 
        System.out.println(s1.name); 
     } 
}
