Using the files you developed for Lab #13, create a Cube object and test its accessor and mutator methods (described below) with a client program.

Notes about processing:

Input - Using a menu system, provide the user with the following choices:

Processing - provide the requested response depending on the menu choice selected. When necessary, prompt for additional input (see below).

Output - if requested, provide the output requested. Should the user request the program stop (see below) terminate the menu and program.

For any test run you should create only a default cube or a cube with the side provided by the user.

A sample session might look like this: Cube Choices: 1. Create default cube 2. Create cube with side provided by user 3. Show volume of the cube 4. Show surface of cube 5. Show side 6. Change side 7. Quit Enter choice: 1 Cube created! Cube Choices: 1. Create default cube 2. Create cube with side provided by user 3. Show volume of the cube 4. Show surface of cube 5. Show side 6. Change side 7. Quit Enter choice: 3 Volume is 8 Cube Choices: 1. Create default cube 2. Create cube with side provided by user 3. Show volume of the cube 4. Show surface of cube 5. Show side 6. Change side 7. Quit Enter choice: 4 Surface is 12 Cube Choices: 1. Create default cube 2. Create cube with side provided by user 3. Show volume of the cube 4. Show surface of cube 5. Show side 6. Change side 7. Quit Enter choice: 5 Side is 2 Cube Choices: 1. Create default cube 2. Create cube with side provided by user 3. Show volume of the cube 4. Show surface of cube 5. Show side 6. Change side 7. Quit Enter choice: 4 Surface is 24 Cube Choices: 1. Create default cube 2. Create cube with side provided by user 3. Show volume of the cube 4. Show surface of cube 5. Show side 6. Change side 7. Quit Enter choice: 7 End of program

Notes about the Cube class:

Constructors - Create two (2) constructors. The first should be a "no argument" constructor that initializes the side(s) to a value of 2.0 (declared as a double). The second constructor will initialize the side of the cube to a value entered by the user.

Accessor Methods -

getSide - returns the value of the side of the cube

getVolume - returns the value of the volume of the cube (the volume is the side3).

getSurface - returns the surface of the cube (a cube has 6 sides, the surface will be the 6 * area of a side, or 6 * side2)

Output -

Display the values requested by the user via the menu. Let the sample program above guide you.
