public String f(int i)
  {
    if(i == 0)
      return "0";

    StringBuffer buffer = new StringBuffer();
    int sign = i /Math.abs(i);
    String s = sign >= 0 ? "" : "-";

    i = i * sign;

    while(i >= 1)
    {
      buffer.append(i % 10);
      i = i / 10;
    }

    buffer.append(s);
    return buffer.reverse().toString();
  }

看看我写的代码,希望对你有帮助
