这算哪种排序？感觉都不像，但是最终可以正确排序。

public static void main(String[] args) {
    int[] a = {11, 454, 21, 2, 9};
    bubbleSort(a);
    System.out.println("结果：" + Arrays.toString(a));
}

private static void bubbleSort(int[] a) {
    for (int i = 0; i < a.length; i++) {
        for (int j = 0; j < a.length; j++) {
            if (a[i] < a[j]) {
                int temp = a[i];
                a[i] = a[j];
                a[j] = temp;
               System.out.println("i-" + i + " j-" + j + "  " + Arrays.toString(a));
}
        }
    }
}

打印结果：

i-0 j-1  [454, 11, 21, 2, 9]
i-1 j-0  [11, 454, 21, 2, 9]
i-2 j-1  [11, 21, 454, 2, 9]
i-3 j-0  [2, 21, 454, 11, 9]
i-3 j-1  [2, 11, 454, 21, 9]
i-3 j-2  [2, 11, 21, 454, 9]
i-4 j-1  [2, 9, 21, 454, 11]
i-4 j-2  [2, 9, 11, 454, 21]
i-4 j-3  [2, 9, 11, 21, 454]
结果：[2, 9, 11, 21, 454]

看打印不像是冒泡， 看代码不像插入排序
