I am also having a problem with my class, i dont understand what is going on as it all looks fine to me.

package javaapplication2;

import java.util.*;
import java.io.*;

public class HighscoreManager {
    // An arraylist of the type "score" we will use to work with the scores inside the class
    private ArrayList<Score> scores;

    // The name of the file where the highscores will be saved
    private final String HIGHSCORE_FILE = "scores.dat";

    //Initialising an in and outputStream for working with the file
    ObjectOutputStream outputStream = null;
    ObjectInputStream inputStream = null;

    public HighscoreManager() {
        //initialising the scores-arraylist
        scores = new ArrayList<Score>();
    }

    public ArrayList<Score> getScores() {
        loadScoreFile();
        sort();
        return scores;
    }

private void sort() {
        ScoreComparator comparator = new ScoreComparator();
        Collections.sort(scores, comparator);
}


public void addScore(int score) {
        loadScoreFile();
        scores.add(new Score(score));
        updateScoreFile();
}

public void loadScoreFile() {
        try {
            inputStream = new ObjectInputStream(new FileInputStream(HIGHSCORE_FILE));
            scores = (ArrayList<Score>) inputStream.readObject();
        } catch (FileNotFoundException e) {
            System.out.println("[Laad] FNF Error: " + e.getMessage());
        } catch (IOException e) {
            System.out.println("[Laad] IO Error: " + e.getMessage());
        } catch (ClassNotFoundException e) {
            System.out.println("[Laad] CNF Error: " + e.getMessage());
        } finally {
            try {
                if (outputStream != null) {
                    outputStream.flush();
                    outputStream.close();
                }

        }
}

        try {
            outputStream = new ObjectOutputStream(new FileOutputStream(HIGHSCORE_FILE));
            outputStream.writeObject(scores);
        } catch (FileNotFoundException e) {
            System.out.println("[Update] FNF Error: " + e.getMessage() + ",the program will try and make a new file");
        } catch (IOException e) {
            System.out.println("[Update] IO Error: " + e.getMessage());
        } finally {

public String getHighscoreString() {
        String highscoreString = "";
	int max = 10;

        ArrayList<Score> scores;
        scores = getScores();

        int i = 0;
        int x = scores.size();
        if (x > max) {
            x = max;
        }
        while (i < x) {
            highscoreString += (i + 1) + "\t\t" + scores.get(i).getScore() + "\n";
            i++;
        }
