Problem with an exercise??

[A.N.H]

Hey all, how are u!!?

While reading my book and answering some exercises i got stuck in this exercise, it kinda easy i just got stuck in a small part. anyways here is the question, for u guys who have Java How to program ( Deitel) its page 282 question 6.29

it basicly says that i have to stimulate a coin tossing app, that in the end calculates the average times the coin landed on its head and on its tail.

here is my code

import java.util.Scanner;
import java.util.Random;;


public class TossCoin 
{
	int NumTails = 0;
	int NumHeads = 0;
	int AverageHeads;
	int AverageTails;
	int Sum = NumTails + NumHeads;
	
	private double CalculateAverage( int x, int y)
	{
		return ( x / y);
	}
	
	private void ToToss()
	{
		Random randomnum = new Random();
		
		if ( randomnum.nextInt(1) == 0)
		{
			NumTails++;
		}
		else
		{
			NumHeads++;
		}
	}
	
	public void Tossed()
	{
		
		
		System.out.println("to stop tossing press <ctrl> z otherwise press any key");
		Scanner input = new Scanner ( System. in );
		
		
		if ( input.hasNext())
		{
			ToToss();
		}
		else
		{
			if ( Sum == 0)
			{
				System.out.println("Average is zero");
			}
			
			else
			{
			System.out.println("Average of Tails is");
			CalculateAverage( NumTails, Sum);
			System.out.println("Average of Heads is");
			CalculateAverage( NumHeads, Sum);
			}
		}
	}
}

now the problem is when i try to run it, and i press any key the program stops, but it is supposed to contenuie and stop only after i press ctrl and z, can someone help me please.

here is the main method if u wants it.

public class TossCoinTest 
{
	public static void main(String args[])
	{
		TossCoin tossed = new TossCoin();
		tossed.Tossed();
		
	}

}

What would happen if you just removed the input scanner? i only skimmed through it, but do you ever take input from the keyboard?

ctrl z will stop whatever program from running regardless of whether or not the program is taking input.(at least in UNIX)

nvm i fixed the problem


i changed some of the code but it works now, plus the code is more elegant, i'll post the new code later.

thanks ice
