What are the methods for implementing a drop-down list in Java?

In Java, implementing a dropdown list is typically done using Swing or JavaFX programming. Here are two methods:

1. Implement a drop-down list using Swing.

import javax.swing.*;
import java.awt.*;
public class DropdownListExample {
 public static void main(String[] args) {
 JFrame frame = new JFrame("Dropdown List Example");
 frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
 String[] options = {"Option 1", "Option 2", "Option 3"};
 JComboBox<String> dropdown = new JComboBox<>(options);
 frame.add(dropdown, BorderLayout.CENTER);
 frame.setSize(300, 200);
 frame.setVisible(true);
 }
}

1. Implement a dropdown list using JavaFX.

import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.ComboBox;
import javafx.scene.layout.VBox;
import javafx.stage.Stage;
public class DropdownListExample extends Application {
 public static void main(String[] args) {
 launch(args);
 }
 @Override
 public void start(Stage primaryStage) {
 primaryStage.setTitle("Dropdown List Example");
 ComboBox<String> dropdown = new ComboBox<>();
 dropdown.getItems().addAll("Option 1", "Option 2", "Option 3");
 VBox vbox = new VBox(dropdown);
 Scene scene = new Scene(vbox, 300, 200);
 primaryStage.setScene(scene);
 primaryStage.show();
 }
}

These are two common methods for implementing dropdown lists in Java, using Swing and JavaFX respectively. Depending on specific requirements, you can choose which method to use.
