我在阅读表单文件时遇到数字格式异常

Question

public class List {

    public static void main(String[] args) {

        //java.util.List<String> slist= new ArrayList<String>();

        try {
                FileInputStream f = new FileInputStream("V:/files/student.txt");
                InputStreamReader reader = new InputStreamReader(f);
                BufferedReader br = new BufferedReader (reader);
                String line = null;
                int id;
                String sname,subname,date;
                while (((line = br.readLine().trim()) != "/0")) {
                String[] parts = line.split(",\\s*");
                id=Integer.parseInt(parts[0]);
                sname=parts[1];
                subname=parts[2];
                date=parts[3];
                System.out.print(id+" "+sname+" "+subname+" "+date);
                System.out.println();
                //slist.add(sname);
                /*System.out.print(line);
                System.out.println();
                slist.add(line);*/
            }
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        //System.out.println(slist);
    } 

}

这是输出
