import java.awt.event。*;
import javax.swing。*;
公共类VocabHelper {
私有JFrame mainFrame;
私人JPanel mainPanel；

解决方案
This is a way to get what you want, you can take this idea and do something like this with a CardLayout and a JFrame. You're asking for JDialogs so I made an example with them:
This example is called a Minimal Complete and Verifiable Example (MCVE) or Runnable Example or a Short, Self Contained, Correct Example (SSCCE) and you should provide something like this on your following questions. I'd also recommend you to take the tour and learn How to ask a good question.
You should also check Making a JOptionPane with 4 options, I also used a ternary operator and you should also read How to make Dialogs, so you can add more complex GUI into them, such as those buttons and a JTextField and images, etc., like: this one or this one or this one, just use Google or the search tool bar on the right top corner of this site.
import java.awt.*;
import javax.swing.*;
public class DialogExamples {
String[] answers = new String[] {"A1", "A2", "A3", "A4"};
String[] questions = new String[] {"Q1", "Q2", "Q3", "Your score: "};
int response = -2; //-2 because I'm not sure what value does response has, -1 or 3 on the last option
int i = 0;
int score = 0;
String message = "";
public DialogExamples() {
do {
message = i < 3 ? questions[i] : questions[i] + score;
while (response != 0) { //Correct answer is A1
response = JOptionPane.showOptionDialog(null, message, "Title",
JOptionPane.DEFAULT_OPTION, JOptionPane.PLAIN_MESSAGE,
null, answers, answers[0]);
}
i++;
score++; //Add your logic
response = -2;
} while (i < questions.length); //i = number of questions
}
public static void main (String args[]) {
DialogExamples de = new DialogExamples();
}
}
This will give you an output similar to these ones, and you might have to edit it to fit your code and remove an error on my code which adds answer buttons even on the last dialog (just add a validation, but I'm only giving you the idea, so it's up to you to do the rest).
The 1st and last dialogs
