public interface Cloneable
Cloneableinterface to indicate to the
Object.clone()method that it is legal for that method to make a field-for-field copy of instances of that class.
Invoking Object's clone method on an instance that does not implement the
Cloneable interface results in the exception
CloneNotSupportedException being thrown.
By convention, classes that implement this interface should override
Object.clone (which is protected) with a public method.
Object.clone() for details on overriding this
Note that this interface does not contain the clone method. Therefore, it is not possible to clone an object merely by virtue of the fact that it implements this interface. Even if the clone method is invoked reflectively, there is no guarantee that it will succeed.
