I shouldn't of taken the online version of this class. I'm trying to setup a continuing while loop if the user inputs a Y to continue but discontinue the loop if the user inputs a N.

Code

import java.util.Scanner;

public class NumberBounds {

public static void main(String[] args) {
Scanner keyboard = new Scanner(System.in);

boolean continueflag = true;

while (continueflag)
{

System.out.println("Enter a number");
int starting_number = keyboard.nextInt();

System.out.println("Enter a Upper Bound");
int upper_bound = keyboard.nextInt();

System.out.println("Enter a addition increment");
int step_size = keyboard.nextInt();
starting_number += step_size;

int count = 0;

while (starting_number <= upper_bound)
{
System.out.print(starting_number + " ");
starting_number += step_size;

count += 1; if ((count % 10) == 0)
System.out.println();
}

System.out.print("Would you like to continue enter Y or N?");
if (Y)
continueflag = false;
}

}
}

What do you expect these lines to do, exactly?

A few problems with the lines irimi pointed out.

1) You're not capturing the users input.
2) If the user says yes they want to continue, why would you set the flag to false?
3) That if statement is not right.

Try taking a look at these lines

Code

System.out.println("Enter a addition increment");
int step_size = keyboard.nextInt();
starting_number += step_size;

And figure out what's happening. Try and do something similar to this but with Strings.

If you're not sure what a String is, google it.
