import javafx.application.Application;
import javafx.application.Platform;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.control.Label;
import javafx.scene.control.TextField;
import javafx.scene.layout.VBox;
import javafx.stage.Stage;

public class Main extends Application {
    public static void main(String[] args) {
        Application.launch(args);
    }

    @Override
    public void start(Stage stage) {
        Label nameLbl = new Label("Enter your name:");
        TextField nameFld = new TextField();

        Label msg = new Label();

        Button sayHelloBtn = new Button("Say Hello");

        sayHelloBtn.setOnAction(e -> {
            String name = nameFld.getText();
            if (name.trim().length() > 0) {
                msg.setText("Hello " + name);
            } else {
                msg.setText("Hello there");
            }
        });

        VBox root = new VBox();

        root.setSpacing(5);

        root.getChildren().addAll(nameLbl, nameFld, msg, sayHelloBtn);

        Scene scene = new Scene(root, 350, 150);
        stage.setScene(scene);
        stage.setTitle("hi");
        stage.show();
    }
