java - 将数组元素相加并将它们存储到另一个数组中？ ( java )

Question

我即将发布的代码片段来自一个程序，该程序应该询问用户一系列多项选择问题。然后，程序将记录每个问题的分数，并将总分存储在另一个数组中。我将有多个玩家玩这个游戏，所以这就是为什么我需要 2 个数组。

这是我所拥有的:

//Asks questions and stores score in array
public static int [] questions ()
{
    userinput=""; //input will be stored in here
    int total[]= new int[100];
    int score[]=new int[5];
    for(int i=0; i < ps.length; i++)
    {
        userinput=JOptionPane.showInputDialog(que[i]); //Outputs a question stored in   another array in another method.
        if (response.equals(ans[i])) //this compares the user input to the correct answer of the question, which is in another method.
        {
            JOptionPane.showMessageDialog(null,"You selected " + " " + ans[i] + " You were correct, 1 point!");
            score[i]=1;
            total[i]=total[i]+score[i];
        }
        else if(!response.equals(ans[i])) // If the answer isn't correct
        {
            score[i]=0; // I want to assign 0 for the question
            JOptionPane.showMessageDialog(null,"You're wrong!, The correct answer was "+ans[i]);
        }
    } // close loop
    return total; // return's this to another method which will do all of the other work
}

我似乎遇到了问题:

JOptionPane.showMessageDialog(null,"You selected " + " " + ans[i] + " You were correct, 1 point!");
score[i]=1;
total[i]=total[i]+score[i];    

如果答案正确，我想为 Score[] 中的每个元素加 1。然后我想累积score[]的总和并将其存储在total[]的每个元素中。我将总计返回到另一个方法，该方法将其存储在数组中。

好吧，看来您需要在方法中传递当前用户的序号，以便它可以计算 total 数组中的正确位置。由于您似乎想要汇总多个问答 session 的总分，因此您需要从外部传递 total:

public static void questions(int userOrdinal, int[] total) {
    final int questionsPerUser = 5;

    userinput = ""; //input will be stored in here
    for (int i = 0; i < questionsPerUser; i++) {
        userinput = JOptionPane.showInputDialog(que[i]); //Outputs a question stored in   another array in another method.
        if (response.equals(ans[i])) //this compares the user input to the correct answer of the question, which is in another method.
        {
            JOptionPane.showMessageDialog(null, "You selected " + " " + ans[i] + " You were correct, 1 point!");
            total[userOrdinal * questionsPerUser + i] = 1;
        } else if (!response.equals(ans[i])) // If the answer isn't correct
        {
            total[userOrdinal * questionsPerUser + i] = 0;
            JOptionPane.showMessageDialog(null, "You're wrong!, The correct answer was " + ans[i]);
        }
    } // close loop
}

抱歉，我仍然不明白为什么你需要 score 数组，因为你的初始代码与 total[i]++ 相同，并且你从未阅读过内容score，只写入它。
