Ok, so I'm taking a class in Java. I've already turned in this assignment but after doing so I got to thinking about a piece of code that I came up with to solve a problem. I was wondering what better way there might be. As a rule (because the class hasn't learned it, though I know it already) we can't use arrays, which I complained to the teacher because I think it would make the whole assigment easier.

Bascially, it's a slot machine, 3 slots and 6 symbols (using text to simulate) at the end I have to count matching slots and pay accordingly. When you see my code you'll see a method that I came up with, but I was wondering if there were an easier way. Mainly because I want to up scale it to 5 slots I can see how I would have to modify my existing code, but not sure if then there was an easier way.

Here's the entire code:
package slot.machine;
 
import java.util.Random;
import java.util.Scanner;
 
public class SlotMachine {
 
    public static void main(String[] args) {
        Scanner kb = new Scanner(System.in);
        Random rnd = new Random();
        int rndSlot1, rndSlot2, rndSlot3, betAmnt, matches, multiplier;
        int totalWinning = 0, totalBet = 0, cntPlays = 0;
 
        do 
        {
            // Let's get the slots first, casino style programming ;)
            rndSlot1 = rnd.nextInt(5);
            rndSlot2 = rnd.nextInt(5);
            rndSlot3 = rnd.nextInt(5);
 
            // Let's (re)set some things
            matches = 0;
            multiplier = 0;
 
            // Get bet from user
            System.out.print("Please enter bet amount (0 to quit): ");
            betAmnt = kb.nextInt();
 
            if(betAmnt > 0) // If they want to play...
            {
                cntPlays++; //Number of games player...just for fun.
                totalBet += betAmnt; // Accumulate total bets
 
                // Display Results
                switch(rndSlot1)
                {
                    case 0:
                        System.out.print("\nCherries ");
                        break;
                    case 1:
                        System.out.print("\nOranges ");
                        break;
                    case 2:
                        System.out.print("\nPlums ");
                        break;
                    case 3:
                        System.out.print("\nBells ");
                        break;
                    case 4:
                        System.out.print("\nMelons ");
                        break;
                    case 5:
                        System.out.print("\nBars ");
                        break;
                    default:
                        // Shouldn't Get here...
                        System.out.print("\nTILT! "); // Or "Error!" or something like that
                        break;
                }
                switch(rndSlot2)
                {
                    case 0:
                        System.out.print("Cherries ");
                        break;
                    case 1:
                        System.out.print("Oranges ");
                        break;
                    case 2:
                        System.out.print("Plums ");
                        break;
                    case 3:
                        System.out.print("Bells ");
                        break;
                    case 4:
                        System.out.print("Melons ");
                        break;
                    case 5:
                        System.out.print("Bars ");
                        break;
                    default:
                        // Shouldn't Get here...
                        System.out.print("TILT! "); // Or "Error!" or something like that
                        break;
 
                }
                switch(rndSlot3)
                {
                    case 0:
                        System.out.println("Cherries");
                        break;
                    case 1:
                        System.out.println("Oranges");
                        break;
                    case 2:
                        System.out.println("Plums");
                        break;
                    case 3:
                        System.out.println("Bells");
                        break;
                    case 4:
                        System.out.println("Melons");
                        break;
                    case 5:
                        System.out.println("Bars");
                        break;
                    default:
                        // Shouldn't Get here...
                        System.out.print("TILT!"); // Or "Error!" or something like that
                        break;
                }
 
                // Count the matches
                if(rndSlot1 == rndSlot2 || rndSlot1 == rndSlot3) matches++;
                if(rndSlot2 == rndSlot3) matches++;
 
                switch(matches)
                {
                    case 0: // No match, no winner
                        multiplier = 0;
                        break;
                    case 1: // 2 match
                        multiplier = 2;
                        break;
                    case 2: // 3 match
                        multiplier = 3;
                        break;
                    default:
                        //Shouldn't get here
                        System.out.println("Sorry, cheaters are losers.");
                        multiplier = 0;
                        break;
                }
                if(multiplier > 0) // See if they won anything this time
                { 
                    totalWinning += (betAmnt * multiplier); // Accumulate Total Winnings
                    System.out.println("\nCongratulations, you've won : $" 
                            + (betAmnt * multiplier));
                } else {
                    System.out.println("\nSorry, please try again");
                }
            }
        } while(betAmnt > 0);
        System.out.println("\nThank you for playing.\n");
        System.out.println("Your total winnings: " + totalWinning);
        System.out.println("Your total bets: " + totalBet);
        System.out.println("You lost/gained: " + (totalWinning - totalBet) 
                + " in " + cntPlays + " pulls.");
    }
}

Particularly these lines:

                // Count the matches
                if(rndSlot1 == rndSlot2 || rndSlot1 == rndSlot3) matches++;
                if(rndSlot2 == rndSlot3) matches++;
 
                switch(matches)
                {
                    case 0: // No match, no winner
                        multiplier = 0;
                        break;
                    case 1: // 2 match
                        multiplier = 2;
                        break;
                    case 2: // 3 match
                        multiplier = 3;
                        break;
                    default:
                        //Shouldn't get here
                        System.out.println("Sorry, cheaters are losers.");
                        multiplier = 0;
                        break;
                }

So, thoughts? What is a better way to find matches between variables (all ints) without over counting (My first code made that mistake, but I fixed it and resubmitted it to my teacher in time)
