What is deep copy? Explain with an example in Java. | Creating an exact copy of an existing object in the memory is known as cloning.
The clone() method of the class java.lang.Object accepts an object as a parameter, creates and returns a copy of it (clones).
In order to use this method, you need to make sure that your class implements the Cloneable interface.
