Using methods in methods ?

[jk91]

Heey,

I would like to know where I'm screwing up in this piece of code. I had a lecture on working with methods today, so I tried to do some assignments.

I'm trying to call a method in a method, but this seems to be impossbile the way I do it.

The purpose of the code is to know find out who can serve more pizza's. Mario uses 3 ingredients on a pizza out of 10 available and Luigi 4 out of 9.

If anyone has got any other tips regarding my way of coding, feel free to shout it out loud :)

Here's what I wrote so far:

package Pizza;
import java.io.PrintStream;

class Pizza {
	
	static final int NUMBERINGREDIENTSMARIO = 10;
	
	static final int NUMBERINGREDIENTSLUIGI = 9;
	
	static final int NUMBERCHOICESMARIO = 3;
	
	static final int NUMBERCHOICESLUIGI = 4;
	
	int a,b,c,d,h,i,j,x,y,options;
	
	PrintStream out;
				
	Pizza() {
		
		out = new PrintStream(System.out);			
		
	}
	
	// bereken de faculteit van een waarde
	
	void Factorial(int x) {	
		
		int factorialOfNumber = 1;
		
		for (int p = 1; p <= x; p++) {
			
		factorialOfNumber *= p;
		
		}
		
		out.printf("Factorial is %d",factorialOfNumber);
		
		return;
		
	} 
	
	// reken voor beide heren de formule uit m.b.v de input van de Factorialfunctie
	
	void Options(int numberIngredients, int numberChoices) {
		
		h = Factorial(numberIngredients);
		
		i = Factorial(numberChoices);
		
		j = Factorial(numberIngredients - numberChoices);
		
		int options = h / (i*j);
		
		return options;
			
	}
	
	// vergelijk de output van beide door options aan te roepen.
	
	void Compare(int a, int b, int c, int d) {
		
		int x = Options(a,b);
		
		int y = Options(c,d);
		
		if(x > y) {
			
			out.print("Mario can serve more pizza's.");
			
		} else {
			
			out.print("Luigi can serve more pizza's.");
			
		}
		
	}
	
	void Start() {
		
		Compare(NUMBERINGREDIENTSMARIO, NUMBERCHOICESMARIO, NUMBERINGREDIENTSLUIGI, NUMBERCHOICESLUIGI);
		
	}
		
	public static void main(String[] args) {

		new Pizza().Start();

	}

}

Thanks in advance !

I would like to know where I'm screwing up in this piece of code.

So would we. How about providing more details. If you get errors then post them.

Hint: A void method returns nothing.

Your hint did it! Thanks for your help. I changed the output of the methods and the program is working fine now.

Thanks again
