给你个思路吧  
排序法
int[] m = {2,10,4,7,5,8,6,9,1,3};
for(int i = 0;i < m.length - 1;i++) //排序次数
{                          
                           //两两比较，实现排序
for(int j = 0;j < m.length - 1 - i;j++)
  {
 if(m[j] < m[j + 1])
  {
                                //交换
    int temp = m[j];
    m[j] = m[j + 1];
    m[j + 1] = temp;
  }
  }
}
