Question

1. Create a String variable named menuChoice. 

2. Display 3 options for your program. I recommend using 3 System.out.println statements and a 4th System.out.print to show "Enter your Selection:". This needs to be inside the do -- while loop.

       A. Deposit Cash.

       B. Withdraw Cash

       X. Exit

       Enter your Selection:

3. Prompt for the value menuChoice.

4. If menuChoice is "A", display "Do Deposit" and redisplay the menu.

    If menuChoice is "B", display "Do withdrawal" and redisplay the menu.

    If menuChoice is "X", the loop needs to terminate.

    If any other choice is given, display "Invalid selection" and redisplay the menu.

For grading, I will test with uppercase characters. Review section 5.1 for String comparisons.

5 point bonus - Convert the menuChoice to an upper case String after input or as part of the input but before any processing is done. This will allow me to enter 'a' but process as 'A'. You can Google for "Java string uppercase" to see how this is done.

5 point bonus - For Task 4 - Create  2 void methods  - 1 for option A to call, and another for option B to call. Do the display work only inside these methods and call these methods for these options.
