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

       System.out.println("Computer has " + compMatch + " of a kind");

     if(playerMatch == 1)

       System.out.println("You have nothing");

     else

       System.out.println("You have " + playerMatch + " of a kind");

           System.out.println("You win");

        else

        {

          if(compHigh > playerHigh)

            System.out.println("Computer's values are higher - computer wins");

     highest = highest + 10 * highValue;

     return highest;
