使用bubble sort排序int成绩数组时 同索引String课程数组出现值覆盖问题

你在交换关联数组元素的步骤中，只完成了课程数组一半的交换逻辑：你将courses[i]覆盖为了courses[i+1]的值，但没有把原courses[i]的值存入courses[i+1]的位置，导致课程编号被批量覆盖，只有前两个未完全触发后续交换的条目保留了正确值。

只需要调整交换逻辑，对课程数组也执行完整的交换操作即可：

// Using bottom to check the smaller list each time
int bottom = marks.length - 1;

// Once there are no more swaps, the list is sorted and it will leave
boolean hadSwap = true;
while (hadSwap) {
    // If there are no more swaps, it will leave
    hadSwap = false;
    
    // Checking ALL elements that could need to be moves
    for (int i = 0; i < bottom; i++) {
    
        // Checking two elements next to eachother to see if they need to be swapped
        if (marks[i] > marks[i + 1]) {
            hadSwap = true;
            // 交换分数数组
            int tempMark = marks[i];
            marks[i] = marks[i + 1];
            marks[i + 1] = tempMark;
            // 同步交换对应的课程数组
            String tempCourse = courses[i];
            courses[i] = courses[i+1];
            courses[i+1] = tempCourse;
        }
    }
    // The final item is in the right spot, shorten the list
    bottom--;
}
