您好，我对 Java 及其所有奇迹非常陌生。当谈到 while 循环和 for 循环时，我完全感到困惑。我很难让我的代码仅打印实数的 n 个用户输入的平均值，然后计算平均值并获得所用输入的高值和低值。并且如果用户键入“结束”停止并计算....我只使用 java 可能 2 周请裸露我的新手我正在努力学习但循环很难让我听到...这是我的到目前为止的代码。

int inputNumber = Integer.parseInt (JOptionPane.showInputDialog("Enter a few real numbers"));
//number entered by user
while (inputNumber !=0) {//numbers entered
    sum += inputNumber;
    count++;//adds one to count for every number entered

    if (count == 7){
        System.out.println("thats enough numbers enter end");
        //stops excess of seven numbers prompts type end to finish
    }
    else {
        average = ((double)sum) / count;//gets average double the numbers divided by number of numbers
        System.out.println("average:"+ average); //displays average

        JOptionPane.showMessageDialog(null, "The average is "       +average + "and the number of numbers entered is " + count);
    }
}

【问题讨论】：

"Enter a few real numbers" 在循环之外，所以它只运行一次。另一方面，"The average is " 在循环内 - 猜猜你希望它在循环外，在输入所有数字之后。

【解决方案1】：

您可以从用户那里获取循环外的输入数，迭代总次数以获得输入和总和，计算总和后计算平均值

    int total = Integer.parseInt(JOptionPane.showInputDialog("Enter total number of inputs "));
    for (int i = 0; i < total; i++) {
        sum += Integer.parseInt(JOptionPane.showInputDialog("Enter input number "));
    }
    average = sum / total;
    JOptionPane.showMessageDialog(null, "The average is " + average + "and the number of numbers entered is " + total);

我试着写一个，希望对你有帮助。我也是 Java 新手。

    int sum = 0;
    int count = 0;
    double average = 0;
    int inputNumber2 = 0;
    //number entered by user
    while (inputNumber2 == 0) {//numbers entered

        int inputNumber = Integer.parseInt (JOptionPane.showInputDialog("Enter a few real numbers"));
        sum += inputNumber;
        count++;//adds one to count for every number entered

        if (count == 7) {
           // System.out.println("thats enough numbers enter end");
            //stops excess of seven numbers prompts type end to finish
            String text3 = JOptionPane.showInputDialog("Thats enough numbers enter end");
            break;
        } else {
            average = ((double) sum) / ((double)count);//gets average double the numbers divided by number of numbers
            System.out.println("average:" + average); //displays average

            JOptionPane.showMessageDialog(null, "The average is " + average + "and the number of numbers entered is " + count);
        }
    }
}
