我试图从BufferedReader类的readLine()方法从文本文件中读取长类型，然后我使用StringTokenizer解析第一个标记(这是长类型编号)，但我面临的异常错误是java.lang.NumberFormatException

这是我的文本文件的一个例子;

2764841629 Quaroten Ilen

1398844030 Orden Nenama

1185252727 Inja Nenaptin

2370429126 Quaren Inaja

1502141743 Otin Una

1993687334 Quarwennaja Nenoten

1015934104 Polen Meritna

2363674760 Otja Ie

1904629749 Neninin Ordja

3047965620 Algnaja Nenja这里是我从文本文件中读取的代码，并将长整型值赋给我的long变量

private void registerData() throws FileNotFoundException{

try {

String regPatName;

String regPatSurname;

long regPatID;

FileInputStream fis = new FileInputStream("src\\assignment_3\\injuredPersonList.txt");

BufferedReader reader = new BufferedReader(new InputStreamReader(fis));

String line;

while( ( line = reader.readLine() ) != null) {

StringTokenizer st = new StringTokenizer(line, " ");

while(st.hasMoreTokens()){

regPatID = Long.parseLong(st.nextToken());

regPatName = st.nextToken();

regPatSurname = st.nextToken();

Patient regPatient = new Patient(regPatName, regPatSurname, regPatID);

hashMethod(regPatient);

}

}

} catch (IOException ex) {

Logger.getLogger(personTest.class.getName()).log(Level.SEVERE, null, ex);

}

}

private void hashMethod(Patient regPatient){

Long idPat = new Long(regPatient.getPatientID());

int keyID;

keyID = (int) Math.sqrt(Integer.parseInt(idPat.toString().substring(0, 5) + idPat.toString().substring(5, 10))) % (50000);

System.out.println(keyID);

}最后这是我面临的错误;
