Slot Machine Project

[nemoisback66]

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.

 	//Assigning value for each symbol

	}

		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.

System.out.println("No Combination")

He probably expected an ';' after this line. Can't help you with the rest of the errors

[nemoisback66]

Thanks probably have a few errors in it. Main problem is to get it to run. Thanks

Should i delete this thread and just keep it in one or the other?

[javajr]

Probably
In SlotMachine.java

The Definition of three methods are missing . so that only the error comes.
You missed the Definition

In slot.java
That contains some constructor and methods are not properly closing u are opened as "{"
and close as "{"
for Example You see the Line 19 on Slot.java

Can you help me with what methods I am missing im completely lost now! I fixed the opening and closing tags.

a bunch of errors are also produced because a member is declared as PayoutMultiplier but used as payoutMultiplier. look out, java is case-sensitive.

Hi fixed that now getting a few different errors!

Thanks very much for that!! It sorted the problem it now actually works!! My next problem is getting the SlotMachine.java to work with it and then also add a loop to the program so it works!! Can you point me in the right direction please??

[nemoisback66]

These are the errors im getting! Thanks for all the help so far begining to understand wer ive went wrong by looking at ur fixed code!! If you could help me with this last bit it would be great!!!

Am i missing any methods? I think this could be the problem!!
