JAVA while loops don't seem to be working?

So i'm trying to create this program that is essentially a dialog between the computer and the user. My while loops don't seem to be functioning. I thought maybe it could be because I have the brackets in the wrong space? Or maybe the boolean conditions I have set for the while loops are not activating? Any help would be hugely appreciated. It should return back to my topics menu if the user doesn't a) enter anything b) does not enter a correct topic c) enters a correct topic, the computer asks a relevant question then returns back to the topic menu...

this is my code:

import javax.swing.*;

public class letsstartatthebasiclevel {
    public static void main(String[] args) {

    // these are my topics / keywords
    String keyword1 = "dungeons";
    String keyword2 = "dragons";
    String keyword3 = "work";
    String keyword4 = "romance";
    String keyword5 = "books";
    String keyword6 = "gardening";
    String keyword7 = "politics";
    String keyword8 = "games";
    String keyword9 = "music";
    String keyword10 = "partying";  //conversation example. Jeeves: have you been to any good parties recently? user answers. Jeeves: thats nice to hear.

    JOptionPane.showInputDialog("Greetings traveller, I am Jeeves");

    String first_name;
    first_name = JOptionPane.showInputDialog("I hope you're well. What is your name?");

    boolean finished = false;
    while (!finished) {
        if (first_name.isEmpty()) {

            first_name = JOptionPane
                    .showInputDialog("I'm sorry I didn't quite catch that. What was your name again?");
        } else
            finished = true;

    }

    // while (first_name.equals(null)) {
    // JOptionPane.showInputDialog("I'm sorry I didn't quite catch that. What was
    // your name again?");

    // }

    JOptionPane.showMessageDialog(null, "Nice to meet you " + first_name);

    JOptionPane.showMessageDialog(null,
            "We can talk about many things, just a moment... I have a list of some topics we could talk about.. where was it..");

    String topics;

    topics = "\ndungeons\ndragons\nwork\nromance\nbooks\ngardening\npolitics\ngames\nmusic\npartying";

    String first_question = JOptionPane.showInputDialog(
            "Ah! Here it is. Is there anything here that tickles your fancy? Just enter the topic you would like to talk about"
                    + topics);

    // create a boolean to make the condition in which the following IF statement
    // will work. boolean answer_dungeons;
    // if answer contains dungeons, then tell the user about dungeons, and return to
    // the topic menu. complete this 10 times for all of the possible topics

    boolean no_topic = false;
    while (!no_topic) {  //it might be better to swap this while loop so that insted of acting on null entry, it acts on keyword entries.
        // so while keyword is detected, then ask a question IF (what keyword is entered), else "i dont know that topic message"
        if (first_question.isEmpty()) {

            first_question = JOptionPane.showInputDialog("It would be great if we both gave this conversation our %110. Just tell me which topic it is you would like to discuss." + topics );
        }
        else no_topic = true;
    }
        boolean topic_menu = false; 
                while(!topic_menu) {
