11.8.1. Object Cloning

Try these first

1. 1.

   What does the clone() method do?

   Hint

   Think of cloning something like a Xerox copy.

2. 2.

   What happens if a class does not implement the Cloneable interface?

   Hint

   Remember what happens when you try to clone without permission?

3. 3.

   What does the clone() method return?

   • A new object instance
   • A reference to the same object
   • A copy of the object

   Hint

   Think about what cloning essentially means.

4. 4.

   True or False: The Cloneable interface is required to clone an object.

   • True
   • False

   Hint

   Consider the requirements before cloning.

5. 5.

   Create a class that models a Rectangle, includes fields for width and height, and implements cloning. Demonstrate the cloning process with a sample main method.

   Hint

   Make sure to test that both rectangles have the same dimensions.

6. 6.

   Think of a scenario in a software application where cloning would be necessary. Describe the class structure and how the cloning would improve the application's design.

   Hint

   Consider how this could enhance user experience without redundancy.
