what use of Object Cloning in Java

By Admin on

The object cloning is a way to create exact copy of an object. For this purpose, clone() method of Object class is used to clone an object.

The java.lang.Cloneable interface must be implemented by the class whose object clone we want to create. If we don't implement Cloneable interface, clone() method generatesCloneNotSupportedException.

The clone() method is defined in the Object class. Syntax of the clone() method is as follows:

  1. protected Object clone() throws CloneNotSupportedException  

The clone() method saves the extra processing task for creating the exact copy of an object. If we perform it by using the new keyword, it will take a lot of processing to be performed that is why we use object cloning.
