Core Java Interview Questions and Answers

Ques. What is Cloneable Interface in Core Java?
Ans. A  clone of an object is an object with distinct identity and equal contents. To define clone, a class must implement cloneable interface and must override Objectís clone method with a public modifier. At this point, it is worth nothing that cloneable interface does not contain the clone method, and Objectís clone method is protected.
When the Object class finds that the object to be cloned isnít an instance of a class that implements cloneable interface, it throws CloneNotSupportedException.
If a class wants to allow clients to clone itís instances, it must override Objectís clone method with a public modifier.
