Thread: Help making a loop please

Take a look at this tutorial to figure out how to get user input: How to Make Dialogs (The Java™ Tutorials > Creating a GUI With JFC/Swing > Using Swing Components)

When you have that part figured out, take a look at this tutorial to figure out how to create a loop: The while and do-while Statements (The Java™ Tutorials > Learning the Java Language > Language Basics)

If you're still having trouble after that, post an SSCCE (that's a link) that demonstrates where you're stuck.

import java.io.FileWriter;
import java.io.IOException;
import java.io.PrintWriter;
 
import javax.swing.JOptionPane;
 
public class users2 {
 
    public static void main(String[] args) throws IOException {
        FileWriter fw = new FileWriter("info.txt", true);
        PrintWriter outputFile = new PrintWriter(fw);
        String Fname; //user first name
        String Lname; //user last name
        String email; //user email address
        int response;
 
 
 
        do {
            //Get user first name
            Fname = JOptionPane.showInputDialog("Enter user first name");
            //Get user last name
            Lname = JOptionPane.showInputDialog("Enter user last name");
 
            //Get user email
            email = JOptionPane.showInputDialog("Enter user email address");
 
            response = moreInputRequest(); //ONLY REQUESTS "ANOTHER?" After details are provided.
 
            outputFile.print(Fname);
            outputFile.print(Lname);
            outputFile.print(email);
 
        } while (response == JOptionPane.YES_OPTION);
        outputFile.close();
 
    }
 
    /*Helper method, returns option pane with input*/
    private static int moreInputRequest() {
        return JOptionPane.showConfirmDialog(null, "Would you like to enter another?",
                "Confirm", JOptionPane.YES_NO_OPTION, JOptionPane.QUESTION_MESSAGE);
    }
}

This should get you going!
Problems you had were:

• outputFile.close() was out of the scope of the declaration
• you were only asking if user would like to go again ONCE, and after that, the same input would be used over and over resulting in an infinite loop if user selected YES.

Hooray spoonfeeding

Not like he didn't show any effort, all that needed doing was rearrangement of his code.

Fair enough, but I personally believe a better way to help him would have been to point out why his program was wrong - or better yet, to simply ask him what happened when he ran it.

The only reason I didn't do this myself was because javapenguin had it covered (I'll give credit where credit is due). I was waiting to see if the OP still had questions after his response because javapenguin's hint might have been enough to give him the "a-ha!" moment that we programmers love. As it is, your response deprives him of that.

I'm not looking to fight about it. It's just my opinion.

Thanks for sharing your solution for other people coming across this Thread.
-Apologies for referring to you as a he, but just can never know on this Internet .
If you're reading this, could you 'Mark as Solved' by going to Thread tools, at the top pane. Thanks.

You should omit "another" in the first int variable named response, but when you re-use it in the loop, keep the "another".(nothing major) XD
well written i like it; in fact, i love it. XD

made this! lol
