2. Write code for the Clone.java with three methods.

a. The first method copies a two-dimensional array which is square (same number of rows and columns). Use the following array:

C. The third method copies a two-dimensional array which is ragged. This method must work for both 2D square and rectangular arrays. Use the following array:

3. Write code for the CloneTester.java.

a. Test each method.

b. Test if the second method works for a 2D square array.

c. Test if the third method works for both 2D square and rectangular arrays.
