Huge headache, ArrayList from Txt File

Question

I'm trying to generate an ArrayList from a text file. But the problem is I have no idea how to go about it properly. This is what I've gotten so far.
import java.io.*;
import java.util.*;
public class reader
          try
               FileReader input = new FileReader("quizscore.txt");
               BufferedReader bufferInput = new BufferedReader(input);
               String line;
               while ((line = bufferInput.readLine ()) !=null )
               String[] result = line.split("\\s");
               for (int x=0; x<result.length; x++)
                    System.out.println(result[x]);
          catch (IOException e)
               System.out.println("Error:" + e);
}That is my data reader which is reading a text file with a buncha numbers like this,
9893 034 009 077 078 020
1947 045 040 088 078 055
2877 055 050 099 078 080
3189 022 070 100 078 077
Now I want to create an ArrayList to put all that data into. I cannot seem to set it up correctly and it's driving me nuts.
class Student
     public int idNum;
     public int quiz1;
     public int quiz2;
     public int quiz3;
     public int quiz4;
     public int quiz5;
     public Student(int id, int q1, int q2, int q3, int q4, int q5)
          this.idNum = id;
          this.quiz1 = q1;
          this.quiz2 = q2;
          this.quiz3 = q3;
          this.quiz4 = q4;
          this.quiz5 = q5;
}Now where would I put the
ArrayList StudentData = new ArrayList();
so that when I read the text file, it automatically writes into the ArrayList formated like the public Student object I have? I was orginally supposed to use the StringTokenizer but after reading the java documentation it suggested I code using the split function. So the question is, how do I get it to write every line's tokens into one array row and so on?

Answer 1

Using turng's code as a sort of guideline, I have created this piece of code. There are some problems though. The array doesn't seem to be writing properly.
import java.io.*;
import java.util.*;
public class getData
     public getData()
     public void load(File file)
          String[][] studentData = new String[40][6];
          try
               FileReader input = new FileReader(file);
               BufferedReader bufferInput = new BufferedReader(input);
               String line;
               while ((line = bufferInput.readLine ()) !=null )
               System.out.println(line);
               //String[] result = line.split("\\s");
               //for (int x=0; x<result.length; x++)
               //     System.out.println(result[x]);
               for (int l = 0; l <40; l++)
                         for (int i = 0; i < 6; i++)
                              String[] tokens = line.split("\\s");
                              for (int x = 0; x<tokens.length; x++)
                                   studentData[l] = tokens[x];
                                   System.out.println("L is:" + l);
                                   //System.out.print("I is:" + i);
                                   System.out.println(studentData[l][i]);
          catch (IOException e)
               System.out.println("Error:" + e);
     public static void main(String arg[])
          (new getData()).load(new File("quizscore.txt"));
Basically what happens when I run through this, it prints this (This is the last portion, I'm assuming it goes from 0-39)

020The actual text file that is being read,
Stud Qu1 Qu2 Qu3 Qu4 Qu5
1234 052 007 100 078 034
2134 090 036 090 077 030
3124 100 045 020 090 070
4532 011 017 081 032 077
5678 020 012 045 078 034
6134 034 080 055 078 045
7874 060 100 056 078 078

3189 022 070 100 078 077
4602 089 050 091 078 060
5405 011 011 000 078 010
6999 000 098 089 078 020It's writing the very last line throughout the whole array. Why is this? I know my loop coding is probably the problem, and I'm trying to draw out the flow on a piece of paper, but it's confusing me more and more. And I do apologize in advance if the error that's causing this is some simple coding error I should have learned before but probably haven't.
