    Default Slot Machine

    Hi all,

    Im new to java this year and have been asked to create a small slot machine program for a project. It is a 3 reel slot machine with a few different combinations of winning. I have came across a few problems when coding this I have listed them below.

    1. The program has yet to start up and run. I keep getting these 3 errors and dont no how to fix them. This is in the main application.

     

    C:\Users\Andy\Desktop\Programming\SlotMachine.java :55: cannot find symbol
    symbol : method compute()
    location: class SlotMachine
    mySlot.compute();
    ^
    C:\Users\Andy\Desktop\Programming\SlotMachine.java :94: cannot find symbol
    symbol : method getwinnings()
    location: class SlotMachine
    winnings = mySlot.getwinnings();
    ^
    C:\Users\Andy\Desktop\Programming\SlotMachine.java :97: cannot find symbol
    symbol : method geteuro()
    location: class SlotMachine
    euro = mySlot.geteuro();




    This is the code i have for this part of the program.

    import javabook.*;
     
    class SlotMachine{
    	public static void main(String args[]){
     
    		//Declare objects
     
    		MainWindow mWindow;
    		InputBox iBox;
    		OutputBox oBox;
    		SlotMachine mySlot;
     
    		//Create objects
     
    		mWindow = new MainWindow();
    		iBox = new InputBox(mWindow);
    		oBox = new OutputBox(mWindow);
    		mySlot = new SlotMachine();
     
    		//Show mWindow & oBox
     
    		mWindow.show();
    		oBox.show();
     
    		//Declare Variables
     
    		int euro;
    		int coin;
    		int winnings;
    		int slot1;
    		int slot2;
    		int slot3;
     
     
     
    		//Get Input
     
    		iBox.getInteger();
    		      System.out.println("Enter amount of coins to bet");
     
    			if (coin == 0){
    					System.out.println("Game has ended");
    }
     
     
    		//process
     
     
    		mySlot.compute();
     
    		if (slot1 == 1){
    			oBox.print("Cherry ");
    	}
    		else if (slot1 == 2){
    			oBox.print("Grape ");
    	}
    		else if (slot1 == 3){
    			oBox.print("Bell");
    	}
     
     
    		if (slot2 == 1){
    			oBox.print("Cherry ");
    	}
    		else if (slot2 == 2){
    			oBox.print("Grape ");
    	}
    		else if (slot2 == 3){
    			oBox.print("Bell");
    	}
     
    		if (slot2 == 1){
    			oBox.print("Cherry ");
    	}
    		else if (slot2 == 2){
    			oBox.print("Grape ");
    	}
    		else if (slot2 == 3){
    			oBox.print("Bell");
    	}
     
     
     
     
     
    		//output
     
    		winnings = mySlot.getwinnings();
    			oBox.println("You have Won");
     
    		euro = mySlot.geteuro();
    			oBox.println("Your coins in Euro");
     
    }
    }

    The other part of the program gives me 2 errors!

     

    1.C:\Users\Andy\Desktop\Programming\Slot.java:44: illegal start of expression
    public void setCoin(int c){
    ^
    2.C:\Users\Andy\Desktop\Programming\Slot.java:151: ';' expected
    ^




    This is the code below.

    import javabook.*;
    import java.util.Random;
     
     
     class Slot{
     	private Random slotNumber = new Random();

    		coin = c;
    }

    	{
     
    	public int getSlot3(){
    			return slot3;
    	{
     
     
     
    	//Compute
     
    		public void compute(){
     
    		int slot1 = slotNumber.nextInt(3) + 1;
    		int slot2 = slotNumber.nextInt(3) + 1;
    		int slot3 = slotNumber.nextInt(3) + 1;
     
    		if (slot1 == bell && slot2 == bell && slot3 == bell){
    			System.out.println("10");
    			payoutMultiplier = 10;
    	}
    		else if (slot1 == grape && slot2 == grape && slot3 == grape){
    			System.out.println("7");
    			payoutMultiplier = 7;
    	}
     
    		else if (slot1 == cherry && slot2 == cherry && slot3 == cherry){
    			System.out.println ("5"):
    			payoutMultiplier = 5;
    	}
     
    		else if (slot1 == cherry && slot2 == cherry && (slot3 == grape || slot3 == bell)){
    			System.out.println ("3");
    			payoutMultiplier = 3;
    	}
     
    		else if (slot1 == cherry && (slot2 == grape || slot2 == bell) && slot3 == cherry){
    			System.out.println ("3");
    			payoutMultiplier = 3;
    	}
     
    		else if ((slot1 == grape || slot1 == bell) && slot2 == cherry && slot3 == cherry){
    			System.out.println ("3");
    			payoutMultiplier = 3;
    	}
     
    		else if (slot1 == cherry && (slot2 == grape || slot2 == bell)  && (slot3 == grape || slot3 == bell)){
    			System.out.println ("1");
    			payoutMultiplier = 1;
    	}
     
    		else if ((slot1 == grape || slot1 == bell) && slot2 == cherry && (slot3 == grape || slot3 == bell)){
    			System.out.println ("1");
    			payoutMultiplier = 1;
     
    	}
     
    		else if ((slot1 == grape || slot1 == bell) && (slot2 == grape || slot2 == bell) && slot3 == cherry){
    			System.out.println ("1"):
    			payoutMultiplier = 1;
     
    	}
     
    		else if ((slot1 == grape || slot1 == bell) && (slot2 == grape || slot2 == bell) && (slot3 == grape || slot3 == bell)){
    			System.out.println ("No Win")
    			payoutMultiplier = 0;
    	}
     
    		else {
    			System.out.println("No Combination")
    	}
    }
     
     
     
    	//Get Method
     
    	public int getWinnings();{
    		int winnings = payoutMultiplier * coins;
    		return winnings;
    	}
     
    	double geteuro();{
    		int euro = (coins * .25);
    		return euro;
    	}

    Any help with this would be much appreciated i also have to add a loop so the program allows the player to keep using the program until they enter zero so if you could also explain were abouts in the program i am to put the loop it would be great.

    Thanks for taking the time to read this.

    Where can I find the javabook import?

    The errors are quite self explanatory. What IDE are you using?

     public int getSlot1(){
            return slot1;
        }
     
        public int getSlot2(){
                return slot2;
        }
     
        public int getSlot3(){
                return slot3;
        }

    Your brackets were off.

    Also, you should have setMethod for every getMethod(). Since you've never set any of the slots, they're all going to return null.

    int slot1 = slotNumber.nextInt(3) + 1;
    int slot2 = slotNumber.nextInt(3) + 1;
    int slot3 = slotNumber.nextInt(3) + 1;

    Oh....you do, but why not have that in the get methods? Those are local variables, and it may not like that you have some earlier with the same name before your constructor.

    private int PayoutMultiplier;

    you don't have it capitalized in one of your methods.

    mySlot = new SlotMachine();

    SlotMachine doesn't seem to have a constructor.

    double geteuro();{
            int euro = (coins * .25);
            return euro;
        }
    double euro = (coins * .25);

    It should be.

    also, it appears you may be missing an ending bracket after this method, so that you'll reach end of file while parsing or something.
