Description

The Cloneable interface provides no functionality; it declares no methods or variables. This interface is simply provided as a way of indicating that an object can be cloned (that is, copied). A class that is declared as implementing this interface is assumed to have overridden the Object class' implementation of clone() with an implementation that can successfully clone instances of the class. The implementation of clone() that is provided by the Object class simply throws a CloneNotSupportedException.

Interface Declaration

public interface java.lang.Cloneable {
}
