If you are trying to clone an object in java and are getting the below compilation error -

Then the reason why you are getting the above compiler error is that you have not followed either 1 or both of the basic required steps for cloning an object in Java, which are -

• STEP 1 - The class of the object being cloned should implement java.lang.Cloneable interface.
• STEP 2 - The class should override clone() method of java.lang.Object class.

Once you implement the above 2 steps in the class of the object being cloned then the compiler error will stop appearing.
