Counting repeating values

Question

I have to record league results and the points against each game and have a total of 84 to record for 15 teams.
I have set it up to record Points, For and Against goals across the page from column C to CH but I have been unable to record the number of times games have been won, lost or drawn.
Is it possible to count each value and have it updated each time Ienter the new results in a new column showing won, lost or drawn?
Any assistance that you can offer will be most appreciated

Answer 1

Here's the code:
I have used a Hashtable to store the value and its number of occurrences. Finally to print the result, I used the toString() method of Hashtable but you can print it in your own way, if u wish.
import java.util.Hashtable;
import java.io.*;
public class Repeating {
     public static void main(String args[]) {
          int[] num = new int[6];
          try {
               BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
               System.out.println("Enter six numbers: (press Enter after each number)");
               for ( int i=0 ; i<num.length ; i++ ) {
                    System.out.print("Enter number #" + i + ": ");
                    num[i] = Integer.parseInt(br.readLine());
               System.out.println("The array is: ");
               for ( int i=0 ; i<num.length ; i++ ) {
                    System.out.print(num[i] + " ");
               System.out.println("");
          } catch (Exception e) {
               System.out.println("Enter only one number in each line ...\n\n");
               e.printStackTrace();
          Hashtable h = new Hashtable();
          for ( int i=0 ; i<num.length ; i++ ) {
               Integer ii = new Integer(num);
               if ( h.containsKey(ii) ) {
                    Integer val = (Integer) h.get(ii);
                    h.put(ii, new Integer(val.intValue() + 1));
               } else {
                    h.put(ii, new Integer(1));
          System.out.println("\nThe result: (value=number of occurrences)");
          System.out.println(h);
