java object

                                The object is a memory space of a class. An object is as software bundle of variables and related methods. In other words, any entity has state and behavior is called as an object.
Example: Mobile, Bus
The java object contains only non-static methods only.By using of object we can access only non-static methods.
The object is an instance of class.

There are four ways to create an object:
 1.       By using new keyword
      2.       By newInstance() method
      3.       By clone() method
      4.       By factory method.


Anonymous object:
                        An object without reference is known as an anonymous object. If one method in a class this is a good approach.

Sample program
public class Student{
    int id;
    public int display(int number){
id=number;
return id;
}
     public static void main(String []args){      
        Student s = new Student();                             //Creating object by using new method
       System.out.println( s.display(123));
       
     }
}
