在乒乓球比赛中数赢 [英] Counting Wins in a Ping Pong game

问题描述

在Scores.java中创建一个带有2个参数的方法:player1Scores和player2Scores.该方法应打印出player1赢得的游戏数和player2赢得的游戏数.

Create a method in Scores.java that takes 2 arguments: player1Scores and player2Scores. The method should print out the number of games player1 won and the number of games player2 won.

这是老师给作业分配的最后一部分，我不知道从哪里开始.我当时在想简单地比较每场胜利，但是那不是Player1Score所能提供的.它仅存储正在进行的游戏的当前分数.我需要能够计算出发生的所有游戏.知道如何将其添加到我的代码中吗?这是到目前为止我正在开发的程序的一个片段.

This is the last part to an assignment given by our teacher and I can't figure out where to start. I was thinking a simple compare each win but thats not provided by the Player1Score. It only stores the current score of the game thats going on. I need to be able to calculate all the games that have happened. Any idea how i could add this to my code? Here is a snippet of the program I'm working on so far.

import java.io.*;
import java.util.ArrayList;
import java.util.List;
import java.util.Scanner;

public class Scores {

public static void main (String args[]) 

{


}
static String allScoresFilename = "allscores.txt";

static String lastScoreFilename = "lastscores.txt";

public boolean writeScores(int player1Score, int player2Score) throws IOException {

PrintWriter scores = new PrintWriter (new File ("Score.txt"));

    scores.println("Player 1 \t Player 2 \n " +player1Score+"\t\t\t " +player2Score);

PrintWriter scores1 = new PrintWriter(new BufferedWriter(new FileWriter("Scores Append", true)));

    scores1.println("Player One:"+player1Score+"\tPlayer Two:"+player2Score);

    scores1.close();

    scores.close();

    return true;

}//End writeScores

public boolean appendScores(int player1Score, int player2Score) throws IOException{

    return true;

}//End appendScores

public void readScores() throws FileNotFoundException

{

    File scores = new File ("Scores Append");

    Scanner fileScanner = new Scanner (scores);

    fileScanner.useDelimiter("[\t|,|\n|\r|:]+");

    String players, player1;

    int numbers, i=0;

    int []p1= new int[10];

    int []p2= new int[10];

    while (fileScanner.hasNext())
    {

        players = fileScanner.next();

        p1[i] = fileScanner.nextInt();

        player1 = fileScanner.next();

        p2[i] = fileScanner.nextInt();

        System.out.println ("p1 is currently "+ p1[i]);

        System.out.println ("p2 is currently "+ p2[i]);

        i++;
    }

}//End readScores

public boolean wins(int player1Score, int player2Score) throws IOException

{

    return true;

}//End wins
}

推荐答案

将这些数组的声明置于readScores()之外，并将其放在类的顶部，以便您可以使用它们调用wins.

Take the declaration for these arrays outside of readScores() and put it at the top of your class so that you can invoke wins with them.

int []p1= new int[10];

int []p2= new int[10];

将wins的签名更改为此:

public void wins(int []player1Scores, int []player2Scores)
{
    int player1Wins = 0;
    int player2Wins = 0;

    for (int i = 0; i < 10; i++)
        (player1Scores > player2Scores) ? player1Wins++ : player2Wins++;

    System.out.printf("Player 1 wins: %-10i Player 2 wins %-10i", player1Wins, player2Wins);
}//End wins

I won't be replying to any comments on this because I'm super busy tonight, but good luck Charles.
