Thread: Finding the lowest integer using sentinellvalue. :( I am stuck!

Hello All,

I am trying to find the lowest integer. I want the user to enter a set of integers and then have the user enter a value to exit the program and have the lowest integer display.

So far, I have the user enter 4 integers and for the fifth integer, the user enters -1. The lowest integer displays.

But what if the user wants to enter 3 integers and have the lowest display?

I don't know what to do in order to make this program work I have sat here at my PC for hours trying to plug in IF statements but nothing works.. ugh!

Here is my code so far:

import java.util.Scanner;
public class Lowjb
{
	public static void main(String [] args)
	{
		double num1;
		double num2;
		double num3;
		double num4;
		double num5= 0;
		double numberCounter;
 
		numberCounter = 0;
 
		Scanner input = new Scanner(System.in);
 
		while(num5!=-1)
		{
		System.out.println("Please enter your first number or enter -1 to exit: " );
		num1 = input.nextDouble();
 
		System.out.println("Please enter your second number or enter -1 to exit: " );
		num2 = input.nextDouble();
 
		System.out.println("Please enter your third number or enter -1 to exit: " );
		num3 = input.nextDouble();
 
		System.out.println("Please enter the fourth number or enter -1 to exit: " );
		num4 = input.nextDouble();
 
		System.out.println("Please enter the fifth number or enter -1 to exit: " );
		num5 = input.nextDouble();
 
 
		double result = minimum(num1, num2, num3, num4);
		System.out.println("The minimum value of the group of numbers is: " + result);
 
		numberCounter = numberCounter+1;
		}
	}
 
	public static double minimum(double a, double b, double c, double d)
	{
		double minimumValue = a;
 
		if(b < a)
			minimumValue = b;
 
		if(c < a)
			minimumValue = c;
 
		if(d < a)
			minimumValue = d;
 
		return minimumValue;
 
	}
}
