Java：具有两个变量的2D数组

我有一个二维数组。我有值

x

和值

y

。我希望每个x可以给每个y一个值。因此，如果存在

1x

和

2y

：

First x, first y: 5 (gives random value)

First x, second y: 3 (3 is a random value)

我希望数组存储数组中每个

x

获得的每个

y

的每个值。这是我得到的，但是它不能像我希望的那样工作：

    int x = Integer.parseInt(JOptionPane.showInputDialog(null, "Insert a value to x"));
    int y = Integer.parseInt(JOptionPane.showInputDialog(null, "Insert a value to y"));
    int[][] array = new int[x][y];
    int counter1 = 0;
    int counter2 = 0;

    while (x > counter1) {
        while (y > counter2) {
            int value = Integer.parseInt(JOptionPane.showInputDialog(null, "Insert a value x gives to the current y"));
            array[counter1][counter2] = value;
        }
        counter1++;
        counter2 = 0;
    }

---

如您所见，我希望

x

和

y

能够变化。我尝试过调试它，但是没有成功。

看起来您忘记了递增

计数器2

。我还建议更改while条件中操作数的顺序，以使代码更具可读性：

while (counter1 < x) {
    while (counter2 < y) {
        int value = Integer.parseInt(JOptionPane.showInputDialog(null, "Insert a value x gives to the current y"));
        array[counter1][counter2] = value;
        counter2++; // added
    }
    counter1++;
    counter2 = 0;
}

for (int counter1 = 0; counter1 < x; counter1++) {
    for (int counter2 = 0; counter2 < y; counter2++) {
        int value = Integer.parseInt(JOptionPane.showInputDialog(null, "Insert a value x gives to the current y"));
        array[counter1][counter2] = value;
    }
}

while（计数器1

当然，for循环更具可读性：

while (counter1 < x) {
    while (counter2 < y) {
        int value = Integer.parseInt(JOptionPane.showInputDialog(null, "Insert a value x gives to the current y"));
        array[counter1][counter2] = value;
        counter2++; // added
    }
    counter1++;
    counter2 = 0;
}

for (int counter1 = 0; counter1 < x; counter1++) {
    for (int counter2 = 0; counter2 < y; counter2++) {
        int value = Integer.parseInt(JOptionPane.showInputDialog(null, "Insert a value x gives to the current y"));
        array[counter1][counter2] = value;
    }
}

for（int counter1=0；counter1

Ah。愚蠢的错误。非常感谢。
