Question
Hello, I’m doing a multi-dimensional array assignment, with with the following requirements
----------------------------------------------------------.
Background:
You have been asked to create a program to score a bowling game. Arrays are to be used. The program should use prompts as specified in these requirements. System.in and System.out should be used (not gui JOptionPane). An object oriented solution should be attempted.
Requirement 1:
Using a one dimensional String array. When the program starts is should prompt the user for the names of the players. It should store the names in a one dimensional array. There can be at most four players (should be stored in a constant). The prompt should be: “Enter player#1 name:” and then repeat with the correct player number until all four are entered.
Requirement 2:
Using a two dimensional int array. Once the user has entered the four player names it should then start prompting for scores for the players. There are 10 ends in a bowling game (should be stored in a constant). The program should use the players name from requirement 1 to prompt for the next score (Text should read: Enter score for John:). The program should loop through each player for end 1, then end 2, continuing until end 10. To be clear, the scores for all four players should be entered for end 1 before starting to prompt for end 2.
Requirement 3:
After each player score is entered, the program should provide a summary of the current scores. This should be accomplished by passing the array to a method and have the method display the results. This should precede the prompt for the next score. (note: if the array and the functionality is in the same class (by your design), you do not have to pass the array to the method).
Requirement 4:
At the end of the scores (ie after all 40 scores are entered), the program should show all of the final scores and add an extra line declaring the winner. The winner declaration should state: “Congratulations John” (if John was the winner).
Sample i/o to be used when getting scored from user:
Current Score
Joe 5 12 15 | 32
Steve 8 17 | 25
Bob 15 12 | 27
Brian 11 12 | 23
Enter score for Steve -->
----------------------------------------------------------
I believe I have Requiremnts 1 & 2 done properly, but I’m not eactly sure how to get the required output, and using 2 classes. Below is my current code, any help would be appreciated.
public class Bowler {
public static void main(String[] args) {
String[] names;
int[][] scores;
int NUM_ENDS = 10;
int NUM_PLAYERS = 4;
Scanner input = new Scanner(System.in);
names = new String[NUM_PLAYERS];
scores = new int[NUM_PLAYERS][NUM_ENDS];
for (int i = 0; i < NUM_PLAYERS; i++) {
System.out.println("Enter player# " + i + " name");
names[i] = input.nextLine();
}
for (int p = 0; p < NUM_ENDS; p++) {
for (int i = 0; i < NUM_PLAYERS; i++) {
System.out.println("Enter Game " + p + " Score for " + names[i]);
scores[i][p] = input.nextInt();
}
}
}
Explanation / Answer
/**
* The java class Bowler that prompts user to
* enter names of the players and scores for
* each player upto 40 scores then print the
* total sum of the each player and then finds
* name of the highest score player and
* print to console*/
//Bowler.java
import java.util.Scanner;
public class Bowler
{
public static void main(String[] args)
{
String[] names;
int[][] scores;
int NUM_ENDS = 10;
int NUM_PLAYERS = 4;
Scanner input = new Scanner(System.in);
names = new String[NUM_PLAYERS];
scores = new int[NUM_PLAYERS][NUM_ENDS];
//create an array of type integer
//to store final scores
int[] finalscores=new int[NUM_ENDS];
int total=0;
for (int i = 0; i < NUM_PLAYERS; i++)
{
System.out.println("Enter player# " + i + " name");
names[i] = input.nextLine();
}
for (int p = 0; p < NUM_ENDS; p++)
{
for (int i = 0; i < NUM_PLAYERS; i++)
{
System.out.println("Enter Game "
+ p + " Score for " + names[i]);
scores[i][p] = input.nextInt();
}
}
//print each player scores and total to console
for (int p = 0; p < NUM_PLAYERS; p++)
{
System.out.printf("%-15s",names[p]);
for (int i = 0; i < NUM_ENDS; i++)
{
total+=scores[p][i];
System.out.printf("%-4d",scores[p][i]);
}
finalscores[p]=total;
System.out.printf("|%-5d",total);
total=0;
System.out.println();
}
//assume that the highscore is the starting player
int highScore=finalscores[0];
String nameOfHighscore=names[0];
//find the highest score player name
for (int p = 1; p < NUM_PLAYERS; p++)
{
if(highScore<finalscores[p])
{
highScore=finalscores[p];
nameOfHighscore=names[p];
}
}
//print the name of high score
System.out.printf("Congratulations "+nameOfHighscore);
}
}
