what is object in java

Comment

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); 
     } 
}

object class java

Comment

The Object class is the parent class of all the classes in java by default.In 
other words, it is the topmost class of java.
The Object class is beneficial if you want to refer any object whose type you 
dont know. Notice that parent class reference variable can refer the child 
class object, know as upcasting.
