气泡排序输出不正确 [英] Bubble sort output is incorrect

问题描述

这是我的冒泡排序代码，但令我感到困惑的是，为什么输出仅显示 125 .

This is my bubble sort code but I am confused why the output shows only 125.

int secondArray[] = {0, 1, 5, 2};
int num;

for (int i = 1; i < secondArray.length; i++) {
    for (int j = 0; j < secondArray.length - i; j++) {
        if (secondArray[j] > secondArray[j + 1]) {
            num = secondArray[j];
            secondArray[j] = secondArray[j + 1];
            secondArray[j + 1] = num;
        }
    }
    System.out.print(secondArray[i]);
}

推荐答案

请运行以下代码:

int secondArray[] = {0, 1, 5, 2};
int num;

for (int i = 0; i < secondArray.length - 1; i++) {
    for (int j = 0; j < secondArray.length - 1 - i; j++) {
        if (secondArray[j] > secondArray[j + 1]) {
            num = secondArray[j];
            secondArray[j] = secondArray[j + 1];
            secondArray[j + 1] = num;
        }
    }
}
for (int number : secondArray) {
    System.out.print(number);
}
