以Java为基础的十类排序算法

    public static void main(String[] args) {
        int[] arr = new int[]{3, 5, 6, 7, 8, 2, 1};
        int i,j;
        for ( i = 0; i <arr.length-1;i++)
        {
            for (j = 0; j<arr.length-1-i;j++)
            {
                if (arr[j] > arr[j + 1])
                {
                    int temp = arr[j+1];
                    arr[j+1] = arr[j];
                    arr[j] = temp;
                }
            }
        }
