一段排序代码 好像有错，但是我自己看不出来

[luojf2003]

final public void Sort(char xchFunction) throws IOException
{
float exchange_Score = 0;
String exchange_ID = "";
String exchange_Name = "";
String strLine = "-------------------------------------";
StudentScore [] n_yossFile;

int Max_iCount = 0;

}

System.out.println("排序结果如下：\n学号\t姓名\t语文\n");
System.out.println(strLine);

System.out.print("\t");

}
break;
......后面的代码差不多
