getting the Id of a button in JavaFX - javafx

Question

I created about 10 buttons in javafx each of them onclick is suppose to change the label field in a certain way. My problem is that I don't want to create 10 different methods for each label I will like to use one method then test the id of the button if correct I preform what I want
example of what I am asking
if (button.id == Info_205_btn) {
System.out.println("clicked");
subject_name.setText("stanly");
}
This is an update after #math answer
Here is the code I did
#FXML
private void chooseSubject() {
for (int i = 0; i < buttonInfo.length; i++) {
buttonInfo[i] = new Button("Info"+i);
buttonInfo[i].setId("Info"+i);
int finalI = i;
buttonInfo[i].setOnAction(event -> checkID(buttonInfo[finalI]));
}
}
#FXML
private void checkID(Button button){
System.out.println("running");
if (button.getId().equals("Info0")) {
System.out.println("clicked");
subject_name.setText("stanly");
}
else if (button.getId().equals("Info1")) {
System.out.println("clicked");
subject_name.setText("stanly1");
}
}
#Override
public void initialize(URL url, ResourceBundle rb) {
chooseSubject();
}
also on click I placed the method chooseSubject in FXML controller

For all of your buttons I think you will still need to put a .setOnAction but you can have them all point to the same function
button.setOnAction(event -> checkID(button));
and from that function check the id
private void checkID(Button button){
if (button.getId().equals("Info_205_btn")) {
System.out.println("clicked");
button.setText("stanly");
}
else if (button.getId().equals("Info_206_btn")) {
System.out.println("clicked");
button.setText("stanly");
}
//So on
}
Also if you put all of your buttons into a list or if they are already in a list you can iterate though the list and do the .setOnAction that way
for (int i = 0; i < buttonList.length; i++)
button[i].setOnAction(event -> checkId((Button) event.getSource()));
Here is a test program I just wrote to give you an example
import javafx.application.Application;
import javafx.geometry.Pos;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.layout.VBox;
import javafx.stage.Stage;
public class Main extends Application {
#Override
public void start(Stage primaryStage) {
Button[] buttonList = new Button[10];
for (int i = 0; i < buttonList.length; i++) {
buttonList[i] = new Button("Button "+i);
buttonList[i].setId("Button"+i);
buttonList[i].setOnAction(event -> checkId((Button) event.getSource()));
}
VBox root = new VBox();
root.setAlignment(Pos.CENTER);
root.getChildren().addAll(buttonList);
Scene scene = new Scene(root);
Stage stage = new Stage();
stage.setWidth(200);
stage.setScene(scene);
stage.show();
}
private void checkId(Button button) {
for (int i = 0; i <= 10; i++) {
if(button.getId().equals("Button" + i))
if(!button.getText().equals("Button " + i + " Clicked"))
button.setText("Button " + i + " Clicked");
else
button.setText("Button " + i);
}
}
public static void main(String[] args) { launch(args); }
}
