The code below works for finding 5, 4, 3 and a pair for dice and compare hands. Now I would like to add a small and large straight and full house..(like a yahtzee hand). I plan on writing methods for the straights and full house...but my questions are:

1. Where would I need to add this in existing code.
2. I assume I would have to once determining either straight or flush I would have to assign a value for it...What would be good?

Some comments appreciated...
public class FiveDice3
{
  public static void main(String[] args)
  {
     final int NUM = 5;
     Die[] comp = new Die[NUM];
     Die[] player =  new Die[NUM];
     int x;
     for(x = 0; x < NUM; ++x)
     {
        comp[x] = new Die();
        player[x] = new Die();
     }
     int compMatch, playerMatch;
     int compHigh, playerHigh;
     String computerName = "Computer";
     String playerName = "You";
     display(computerName, comp, NUM);
     display(playerName, player, NUM);
     compMatch = howManySame(comp, NUM);
     playerMatch = howManySame(player, NUM);
     compHigh = compMatch / 10;
     playerHigh = playerMatch / 10;
     compMatch = compMatch % 10;
     playerMatch = playerMatch % 10;
     if(compMatch == 1)
       System.out.println("Computer has nothing");
     else

1. add a method (or define an interface and a class) for each check thats required.
