Noob problem..

[Jack Nutkins]

Hi, I've recently started to program in java...and I have a problem with some code I've written and I can't see where the problem is.

I get the following error:

int cannot be dereferenced

Here is my code:

import java.io.*;
import java.util.ArrayList;
import java.net.URL;
import java.net.URISyntaxException;
import java.util.*;

public class Phit_Farm
{
    // instance variables
    private static final String F = "phitfarm.txt";
    private ArrayList<Member> members;

    public static void main (String[] args)
    {
        try
        {
            BufferedReader r = new BufferedReader(new FileReader(F));
            String nextLine = r.readLine();
            while (nextLine != null)
            {
                                        StringTokenizer st = 
            new StringTokenizer(nextLine, ",");
        String lastName = (st.nextToken());
        String firstName = (st.nextToken());
        String sex = (st.nextToken());
        String date = (st.nextToken());
        int score1 = Integer.parseInt(st.nextToken());
        int score2 = Integer.parseInt(st.nextToken());
        int score3 = Integer.parseInt(st.nextToken());
        int score4 = Integer.parseInt(st.nextToken());
        int score5 = Integer.parseInt(st.nextToken());
        int score6 = Integer.parseInt(st.nextToken());
        int score7 = Integer.parseInt(st.nextToken());
        int score8 = Integer.parseInt(st.nextToken());
        int score9 = Integer.parseInt(st.nextToken());
        int score10 = Integer.parseInt(st.nextToken());
        Member m = new Member(lastName, firstName, sex, date, score1, score2, score3, score4. score5, score6, score7, score8, score9, score10);
                    
        addMember(m);
        
                nextLine = r.readLine();
            }
        }
        catch (Exception e)
        {
            System.exit(1);
        }
            
            
    }
}

BlueJ tells me the error is on this line:

Member m = new Member(lastName, firstName, sex, date, score1, score2, score3, score4. score5, score6, score7, score8, score9, score10);

Any help would be much appreciated

Can you give us the exact error message? There is nothing being dereferenced at that line.

Yeh bluej is a bit messed up in that respect. If its not on that line then it will be on the line above. As the lines above are all similar then I have a feeling it's somewhere on the lines scores 1 - 10.
The exact error message is as said above:

int cannot be dereferenced

Somewhere you have an int variable, let's call it x for now, which you are trying to dereference:

x.y

where y is either a field or a method. The compiler will tell you the exact line.

The exact error message is as said above:

int cannot be dereferenced

That doesn't say anything... Of course, an int can't be dereferenced. You need the full error message from the compiler. And if BlueJ is not showing you the error, and compile it by hand.

score3, score4. score5,

This might be the cause of the problem (in the line where you create the Member).

Good eye! Indeed, that period ought to be a comma, and that is definitely the source of the error message.
