Object Cloning

Shallow Cloning

A obj = new A();
obj.i = 5;
obj.j = 6;

A obj1 = obj; //Shallow cloning

The object is only one. We have just created two references to the same object.

Deep Cloning

A obj1 = new A();
obj1.i = obj.i;  //Deep
obj1.j = obj.j;  //Cloning

• We create a new object and manually copy all members one by one.
• Not very efficient if there are too many data members.
