im building a stop watch with a digital and analog clock but having trouble with printing the digital clock value mainly because im unsure how to pass the string to the FXML.
why is it that when i try to us id="digitalText" for the textfield in the fxml the program fails but if i were to write it using a text="00:00" it will work properly(just with a text with 00:00 though so no updating the digital clock of course). i would have hoped giving it the id would print the value inside it.
the controller
package tds7xbstopwatchfxml;
import java.awt.TextField;
import java.net.URL;
import java.util.ResourceBundle;
import javafx.animation.Animation;
import javafx.animation.KeyFrame;
import javafx.animation.Timeline;
import javafx.event.ActionEvent;
import javafx.fxml.FXML;
import javafx.fxml.Initializable;
import javafx.scene.image.Image;
import javafx.scene.image.ImageView;
import javafx.util.Duration;
public class FXMLDocumentController implements Initializable {
@FXML
private ImageView clockFace;
@FXML
private ImageView hand;
@FXML
private TextField digitalText;
String digital;
Double rotation = 0.0;
Integer ms = 00;
Integer mm = 00;
Timeline timeline = new Timeline(
new KeyFrame(Duration.millis(1000), (ActionEvent actionEvent) -> {
updateTimer();
updateDigital();
})
);
@FXML
private void stopButton(ActionEvent event) {
timeline.stop();
}
@FXML
private void startButton(ActionEvent event) {
timeline.play();
}
@FXML
private void resetButton(ActionEvent event) {
rotation = 0.0;
ms = 0;
mm = 0;
hand.setRotate(0);
digital="00:00";
timeline.stop();
}
public void updateTimer() {
ms += 1000;
if (ms >= 60000) {
ms = 00;
mm++;
}
rotation = (ms / 60000.0) * 360.0;
hand.setRotate(rotation);
}
public void updateDigital(){
if(ms/1000<10 && mm<10){
digital=("0" + String.valueOf(mm) + ":" + "0" + String.valueOf(ms/1000));
}
if(ms/1000>=10 && mm <10){
digital=("0" + String.valueOf(mm) + ":" + "" + String.valueOf(ms/1000));
}
if(mm>=10 && ms/1000<10){
digital=("" + String.valueOf(mm) + ":" + "0" + String.valueOf(ms/1000));
}
if(mm>=10 && ms/1000>=10){
digital=("" + String.valueOf(mm) + ":" + "" + String.valueOf(ms/1000));
}
}
@Override
public void initialize(URL url, ResourceBundle rb) {
clockFace.setImage(new Image(this.getClass().getResourceAsStream("clockface.png")));
hand.setImage(new Image(this.getClass().getResourceAsStream("hand.png")));
timeline.setCycleCount(Animation.INDEFINITE);
digitalText.setText(digital);
}
}
i know there are better ways to implement the code for the digital clock but mainly i want to know about passing a changing string to be printed. the digitalText.setText(digital); will cause it to crash
and the fxml

You imported the Swing TextField, not the JavaFX text field
Change
import java.awt.TextField
to
import java.scene.control.TextField;
