CIS 120-101 / Overstreet / Fall 2007
Lab 9 – Due: Week 10 (Wed 10/24/07)
Problem Description:
Design and implement a Java program with a class called “Lab9” that will keep track of the number of
points scored by two players in a series of games and display a game by game comparison of who scored
more points. The program will ask the user to input the number of games played. Then ask for the name of
each of the players. The players’ will then be prompted to enter their points scored for each game. The
points scored by each player will be compared for each game. Finally, a dialog box will display which
player scored more points and how many more points they scored for each game played. If the players
score the same number of points, the output will indicate that outcome.
Error Checking:
The program must force the user to enter a positive number of games (0 is not a positive number). You
must also handle the case of the user clicking cancel when asked for any input. If cancel is clicked, a
message should be indicated that cancel was clicked and the program should exit. You do not have to check
for non-integer input for number of games or points scored.
Coding Requirements
You must store each player’s points in an array.
The title bar of your output must display the same information as the example output with the exception
that you will replace Faculty with your first and last name.
You must have the following user-defined methods in your program.
Method Signature and Return Type
Purpose
void inputScores(int[ ] , String )
Prompts the user to enter a score for each game. An
array to hold the player’s scores and the player’s name
will be passed to this method.
void compareScores(int[], int[] , String, String)
Compares the scores of the two player’s game by
game and outputs which player scored more points
and by how much. If the players score the same
number of points, the output will indicate that
outcome. (See example output) The two arrays
holding each player’s scores and their names will be
passed to this method.
Filename Requirements:
Your program must be saved to a file called Lab9.java
You must submit a printed and electronic (CD or Floppy) copy of your commented program along
with a printed copy of your problem analysis, pseudocode, completed data dictionary, completed test
design table and screen captures of the input and output for all test runs in a manila envelope.
Problem Analysis - all inputs, processes, and outputs described. You must also include any formulas or
constants in the problem analysis.
Pseudocode – These steps should be detailed enough for you to transform each English-like statement into
Java statements.
