Thread: Returning to a loop after showConfirmDialog.

SOLVED. thanks snowguy13!!

Hello everyone. I'm currently working on an assignment that requires me to have a loop counting votes until q is entered to activate a dialog box asking if I really want to quit. If I hit yes, the program ends and votes are tallied. If I hit any other key, it goes back to the first loop where it counts votes. I'm having trouble with this because when I set up the showConfirmDialog box, I have to use a while loop. When I do this, I have already left the scope of the first while loop and do not know how to re-enter it.

Can someone help me out with this? I just need advice, I don't want the code written for me or anything. Thank you.

public class VoteCount {
 
public static void main(String[] args) {
 
int yesVotes = 0, noVotes = 0, totalVotes = 0;
char vote;
{
    do {
 String voteString = JOptionPane.showInputDialog(null, "Enter 'Y' to vote yes, 'N' to vote no, or 'Q' to quit voting");
 vote = voteString.charAt(0);
 if (vote == 'Y' || vote == 'y')
     yesVotes++;
 if (vote == 'N' || vote == 'n')
     noVotes++;
    }
    while (vote != 'Q' && vote != 'q');
}
totalVotes = yesVotes + noVotes;
if (vote == 'Q' || vote == 'q')
{
    int reply = 1;
  while (reply != JOptionPane.YES_OPTION)
    reply = JOptionPane.showConfirmDialog(null, "Quit?", "Warning!", JOptionPane.YES_NO_OPTION);
    if (reply == JOptionPane.YES_OPTION)
        JOptionPane.showMessageDialog(null, "yes " + yesVotes + " no " + noVotes + " total " + totalVotes);
 
 
}
}
}

package javaapplication16;
 
 import javax.swing.JOptionPane;
 
 public class VoteCount {
 
 public static void main(String[] args) {
 
 int yesVotes = 0, noVotes = 0, totalVotes = 0;
 totalVotes = yesVotes + noVotes;
 char vote;
 int reply = 1;
 {
     do {
    String voteString;
   voteString = JOptionPane.showInputDialog(null, "Enter 'Y' to vote yes, 'N' to vote no, or 'Q' to quit voting", "Vote Now!", JOptionPane.OK_CANCEL_OPTION);
   vote = voteString.charAt(0);
     if (voteString == null || voteString.length() == 0)
            vote = 'q';
   if (voteString.toLowerCase().equals("y"))
         yesVotes++;
  if (voteString.toLowerCase().equals("n"))
         noVotes++;
 
        { 
    }
 
 if (voteString.toLowerCase().equals("q"))
 {
      reply = JOptionPane.showConfirmDialog(null, "Quit?", "Warning!", JOptionPane.YES_NO_OPTION);
     if (reply == JOptionPane.YES_OPTION)
         JOptionPane.showMessageDialog(null, "yes " + yesVotes + " no " + noVotes + " total " + totalVotes);
     else if (reply != JOptionPane.YES_OPTION);
 continue;
         }
      } while (reply != JOptionPane.YES_OPTION);
 
     }
     }
 }

Here's the simplest thing I can think of: put the confirmDialog inside your first while statement. Then, if the user clicks "No", you can tell the program to just ccontinue to the next while iteration. If the user clicks "Yes", you can use a break statement, then write some code after the while loop that you want the program to execute before ending.

Note: using a

continue;

statement makes the program skip all the code in the loop after it and start at the beginning of the loop's code.

break;

makes the program exit the loop completely and execute whatever code is after the loop.

So to reiterate, I think you only need one while loop.

Hopefully this helps!

package javaapplication16;

import javax.swing.JOptionPane;
 
public class VoteCount {
 
public static void main(String[] args) {
 
int yesVotes = 0, noVotes = 0, totalVotes = 0;
totalVotes = yesVotes + noVotes;
char vote;
{
    do {
 String voteString = JOptionPane.showInputDialog(null, "Enter 'Y' to vote yes, 'N' to vote no, or 'Q' to quit voting");
 vote = voteString.charAt(0);
 if (vote == 'Y' || vote == 'y')
     yesVotes++;
 if (vote == 'N' || vote == 'n')
     noVotes++;
        {
    }
 
if (vote == 'Q' || vote == 'q')
{
    int reply = 1;
    reply = JOptionPane.showConfirmDialog(null, "Quit?", "Warning!", JOptionPane.YES_NO_OPTION);
    if (reply == JOptionPane.YES_OPTION)
        JOptionPane.showMessageDialog(null, "yes " + yesVotes + " no " + noVotes + " total " + totalVotes);
    else if (reply != JOptionPane.YES_OPTION);
    continue;
        }
    } while (vote != 'Q' && vote != 'q');
 
    }
    }
}
 
Is this sort of what you're telling me to do? I got rid of the second while and combined them, then I put the continue after the else if statement should they answer anything but yes. When I run this, however, the program just ends after I hit "no".
 
Thank you! It does help, quite a bit in fact. I feel like I've almost got this one.
