Having trouble with a while loop that gets a certain series of numbers from an input
JamesR
I'm trying to half the input if it % 12 == 0, but if it isn't then you multiply it by 3 and add 1 onto the sum.
The question that I'm working off is: http://i.imgur.com/VzuPtZJ.png
With the code I have currently(which is below), if I enter 12, like in the question I start off with 6, but then the results begin to go wrong and then they go insanely wrong with values in the millions and negative millions etc.
import java.util.*;
public class sheet12t3
{
public static void main(String[] args)
{
Scanner in = new Scanner(System.in);
System.out.print("Enter a number: ");
int aNumber = Integer.parseInt(in.nextLine());
hailstone(aNumber);
}
public static void hailstone(int x)
{
int count = 1;
int max = 0;
String results = "Hailstone series for the number " + x + " is ";
while (x >= 1)
{
if (x % 12 == 0)
x = x / 2;
else
x = 3 * x + 1;
count++;
results += + x + ", ";
if (x > max)
max = x;
}
results += "a total of " + count + " numbers in this sequence with a maximum value of " + max;
System.out.print(results);
}
}

The question says divide by two if the number is even. But you divide by 2 only when it is dividable by 12.
Change this line
(x % 12 == 0)
to
(x % 2 == 0)
And change while (x >= 1) to while (x > 1)
