Part 1: Bank Charges [30 points]

A bank charges $10 per month plus the following check fees for a commercial checking account:

$.10 for each check if less than 20 checks were written

$.08 for each check if 20 through 39 checks were written

$.06 for each check if 40 through 59 checks were written

$.04 for each check if 60 or more checks were written

The bank also charges an extra $15 if the account balance falls below $400 (before any heck

fees are applied).

Write a program that asks for the beginning balance and the number of checks written. Compute

and display the banks service fees for the month.

Name the source code file Bank Charges.java

Here are sample runs of the program:

Part 2: Game (scissor, rock, paper) [30 points]

Write a program that plays the popular scissor-rock-paper game. (A scissor can cut a paper, a

rock can knock a scissor, and a paper can wrap a rock.) The program randomly generates a

number 1, 2, or 3 representing scissor, rock, and paper. The program prompts the user to enter a

number 1, 2, or 3 and displays a message indicating whether the user or the computer wins,

loses, or draws.

NOTE: present user with option to exit the game and do so if they choose this.

Name the source code file RockGame.java

Background

Rock-paper-scissors is a hand game usually played by two people, where players simultaneously

form one of three shapes with an outstretched hand. The "rock" beats scissors, the "scissors" beat

paper and the "paper" beats rock; if both players throw the same shape, the game is tied.

Rock, Paper, Scissors (see http://en.wikipedia.org/wiki/Rock_paper_scissors) is a popular game.

Here are sample runs:
