    Default Array problem

    I am trying to write code to store integers (scores), print them out, and then display the number of scores entered. However, if you enter 3 integers it displays the 3 you entered, 2 zero's, and then tells you you entered 4 scores?! Im very confused here and have tried various if statements, loops, decrementors, etc and I am still at a loss for a solution.

    Any help would be appreciated!!

    Java Code:
    import javax.swing.*;
    public class Scores {
      private final static int SIZE = 25;
      public static void main(String[] args)  {
        int [] scores = new int[SIZE];
        int count = 0;
        double average = 0.0;
        count = loadArray(scores);
        average = determineAverage(scores, count);
        displayResults(scores, count, average);
    //returns the count of the scores entered
      private static int loadArray(int[]n)  {
      	int s = 0;
      	int i;
    s = Integer.parseInt(JOptionPane.showInputDialog(null, "Input test score"));
    if(s == -1){
    	break ;
    } else {
    	n[i] = s;
    	return(i+1);  // so file compiles
    //displays all of the results
     private static void displayResults(int[] n, int cnt, double ave)  {
      	for(int i = 0; i<=cnt; i++){
      		if(n[i]%10 == 0){
    	System.out.println("The total number of test scores" + cnt);
    //	int outstanding = determineOutstanding(0);
    	//System.out.println("The number of Outstanding Scores" + outstanding);

    And also if this is the complete class you've written, seems to me that you've not compile the code.

    1. Closing bracket of the class is missing.

    2. I can't see the method determineAverage is implemented in your class.

    3. In loadArray I can't see that variable i is not initialize before use.

    Don't you notice those things?
