如何在java中跳出全屏模式？

import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.layout.StackPane;
import javafx.stage.Stage;

public class FullScreenJavaFX extends Application {

    @Override
    public void start(Stage primaryStage) {
        Button exitFullScreenButton = new Button("Exit Full Screen");
        exitFullScreenButton.setOnAction(event -> primaryStage.setFullScreen(false));

        StackPane root = new StackPane(exitFullScreenButton);
        Scene scene = new Scene(root, 800, 600);

        primaryStage.setTitle("JavaFX Full Screen Example");
        primaryStage.setScene(scene);
        primaryStage.setFullScreen(true);
        primaryStage.show();
    }

    public static void main(String[] args) {
        launch(args);
    }
}

import javax.swing.*;
import java.awt.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

public class FullScreenSwing extends JFrame {

    public FullScreenSwing() {
        JButton exitFullScreenButton = new JButton("Exit Full Screen");
        exitFullScreenButton.addActionListener(new ActionListener() {
            @Override
            public void actionPerformed(ActionEvent e) {
                dispose();
            }
        });

        JPanel panel = new JPanel();
        panel.add(exitFullScreenButton);

        setContentPane(panel);
        setUndecorated(true);
        setExtendedState(JFrame.MAXIMIZED_BOTH);
        setVisible(true);
    }

    public static void main(String[] args) {
        SwingUtilities.invokeLater(new Runnable() {
            @Override
            public void run() {
                new FullScreenSwing();
            }
        });
    }
}
