谁能帮忙解释一下这段Java加密代码的原理，自己分析了一下不是很懂

  public static String getSig(String[] paramArrayOfString, String paramString)
  {
    int i = 0;
    Object localObject;
    if (i >= paramArrayOfString.length)
    {new StringBuffer();
      i = 0;
    }
    for (;;)
    {
      if (i >= paramArrayOfString.length)
      {
        ((StringBuffer)localObject).append(paramString);
        return Md5.toMD5(((StringBuffer)localObject).toString());
        int j = paramArrayOfString.length - 1;
        for (;;)
        {
          if (j <= i)
          {
            i += 1;
            break;
          }
          if (paramArrayOfString[j].compareTo(paramArrayOfString[(j - 1)]) < 0)
          {
            localObject = paramArrayOfString[j];
            paramArrayOfString[j] = paramArrayOfString[(j - 1)];
            paramArrayOfString[(j - 1)] = localObject;
          }
          j -= 1;
        }
      }
      ((StringBuffer)localObject).append(paramArrayOfString[i]);
      i += 1;
    }
  }

这代码的易读性，还是建议别看了

你确定这代码没问题？可以跑了吗？
