• An interface does not contain any instance field.
• An interface cannot be extended by a class.

Object Cloning:

Object cloning is the process of creating an exact copy of the object with different name. The clone() method present in the object class is use to create clone.

Cloneable Interface:

The Cloneable interface is an interface that specifies that specifies than an object can be cloned.

Syntax:

The Cloneable interface is can be defined as follows:

package java.lang;

public interface cloneable

{

//interface body

}
