Question

这项任务的基本思想是创建一个程序，该程序可以提供摘要并识别谁赢得了＃34;匹配＆＃34;在体育赛事（足球，篮球，足球，棒球等）

**This is my code:**
`import java.util.Scanner;

public class Team {
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);

        // Ask questions about the game type etc.
        System.out.println("Please enter game name: ");
        String gameName = sc.next();
        System.out.println("Please enter " + gameName + " team 1 name: ");
        String t1N = sc.next();
        System.out.println("Please enter " + gameName + " team 2 name: ");
        String t2N = sc.next();
        System.out.println("What is a score in " + gameName + " called? ");
        String scoreName = sc.next();
        System.out.println("How many points per " + scoreName + " in " + gameName + "?");
        int scoreValue = sc.nextInt();
        System.out.println("What is a period in " + gameName + " called?");
        String periodName = sc.next();
        System.out.println("How many " + periodName + " in " + gameName + "?");
        int numberOfPeriods = sc.nextInt();
        int sum1 = 0;
        int sum2 = 0;
        for (int i = 1; i <= numberOfPeriods; i++) {
            System.out.println(periodName + " #" + i);
            System.out.println("How many " + scoreName + " for " + t1N + "?");
            int numberOfScoresT1[] = new int[sc.nextInt()];
            System.out.println("How many " + scoreName + " for " + t2N + "?");
            int numberOfScoresT2[] = new int[sc.nextInt()];

            for (int counter = 0; counter < numberOfScoresT1.length; counter++)
                sum1 += numberOfScoresT1[counter];

            for (int counter = 0; counter < numberOfScoresT1.length; counter++)
                sum2 += numberOfScoresT2[counter];
        }
        System.out.println("Team 1 scored " + sum1 + " team 2 scored " + sum2);

    }`

这是我收到的错误： 请输入游戏名称：足球请输入足球队1名：海豚请输入足球队2名称：美洲虎什么是Fotball的得分叫什么？接地在Fotball中每次触地得分多少分？ 7 什么是Fotball中的一个时期？ 25美分硬币 Fotball多少个季度？ 4 第1季海豚的触地得分有多少？ 3 美洲虎有多少触地得分？ 2 线程＆＃34; main＆＃34;中的例外情况java.lang.ArrayIndexOutOfBoundsException：2 在Team.main（Team.java:36）

我认识到我使用的阵列都在for循环中，我认为这是造成问题的原因，但我不确定如何修复它。

这是一个示例输出应该看起来像：第1季：海豚有多少次达阵？ 2 充电器有多少次达阵？ 1

第二季度：海豚有多少次达阵？ 0 充电器有多少次达阵？ 1

第3季：海豚有多少次达阵？ 0 充电器有多少次达阵？ 2

第四季度：海豚有多少次达阵？ 3 充电器有多少次达阵？ 0

足球比赛结果：

海豚队以35分的成绩获得5次达阵充电器以28分的成绩获得4次达阵

海豚以7分获胜！

Answer 1

for (int counter = 0; counter < numberOfScoresT1.length; counter++)
                sum2 += numberOfScoresT2[counter];

循环的第二个参数是

for (int counter = 0; counter < numberOfScoresT2.length; counter++)

看到你正在访问正文中的numberOfScoresT2数组。

Answer 2

你的内部for循环应该如下

        for (int counter = 0; counter < numberOfScoresT1.length; counter++)
            sum1 += numberOfScoresT1[counter];

        for (int counter = 0; counter < numberOfScoresT2.length; counter++)
            sum2 += numberOfScoresT2[counter];

你在第二个内部for循环中使用了数组numberOfScoresT1的长度而不是数组numberOfScoresT2。

import java.util.Scanner;

public class Team {
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);

        // Ask questions about the game type etc.
        System.out.println("Please enter game name: ");
        String gameName = sc.next();
        System.out.println("Please enter " + gameName + " team 1 name: ");
        String t1N = sc.next();
        System.out.println("Please enter " + gameName + " team 2 name: ");
        String t2N = sc.next();
        System.out.println("What is a score in " + gameName + " called? ");
        String scoreName = sc.next();
        System.out.println("How many points per " + scoreName + " in " + gameName + "?");
        int scoreValue = sc.nextInt();
        System.out.println("What is a period in " + gameName + " called?");
        String periodName = sc.next();
        System.out.println("How many " + periodName + " in " + gameName + "?");
        int numberOfPeriods = sc.nextInt();
        int sum1 = 0;
        int sum2 = 0;

        int numberOfScoresT1[] = new int[numberOfPeriods];
        int numberOfScoresT2[] = new int[numberOfPeriods];

        for (int i = 0; i <numberOfPeriods; i++) {
            System.out.println(periodName + " #" + i);

            System.out.println("How many " + scoreName + " for " + t1N + "?");
            numberOfScoresT1[i] = sc.nextInt();

            System.out.println("How many " + scoreName + " for " + t2N + "?");
            numberOfScoresT2[i] = sc.nextInt();

        }
        sc.close();

        for (int counter = 0; counter < numberOfPeriods; counter++) {
            sum1 += numberOfScoresT1[counter];
            sum2 += numberOfScoresT2[counter];
        }

        System.out.println("Team 1 scored " + sum1 + " team 2 scored " + sum2);

    }
}
