使用其他类中的按钮打开JOptionPane

import javax.swing.*;

public class OptionDialogExample {
    public static void main(String[] args) {
        String[] options = {"Yes", "No", "Cancel"};

        int choice = JOptionPane.showOptionDialog(null,
                "Do you want to continue?",
                "Confirmation",
                JOptionPane.DEFAULT_OPTION,
                JOptionPane.QUESTION_MESSAGE,
                null,
                options,
                options[0]);

        if (choice == 0) {
            System.out.println("User clicked Yes");
        } else if (choice == 1) {
            System.out.println("User clicked No");
        } else if (choice == 2) {
            System.out.println("User clicked Cancel");
        }
    }
}
