Copy Constructor

we can copy the values of one object to another like copy constructor in C++.

There are many ways to copy the values of one object into another in java. They are:

• By constructor
• By assigning the values of one object into another
• By clone() method of Object class

we are going to copy the values of one object into another

ex..

class Student6{  

    int id;  

    String name;  

    Student6(int i,String n){  

    id = i;  

    name = n;  

    }  

      

    Student6(Student6 s){  

    id = s.id;  

    name =s.name;  

    }  

    void display(){System.out.println(id+" "+name);}  

   

    public static void main(String args[]){  

    Student6 s1 = new Student6(1,"abc");  

    Student6 s2 = new Student6(s1);  

    s1.display();  

    s2.display();  

   }  

}
