public interface Cloneable
CloneNotSupportedException exception in my previously explained post.
Applications that override the
clone method can also throw this exception to indicate that an object could not or should not be cloned.
A class implements the
Cloneable interface 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. See Object.clone() for details on overriding this method.
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.
In summary, this can be avoided by implementing Cloneable Interface and Overriding protected method clone().
