Int Value into text Field

In JavaFX, I have a TextField Called "randomIntegerField" I need to auto populate this textfield JavaFX with an integer value returned by a method when i clik on a button.

Here is the method which return the int Value

private int randomNum(){
     Random random = new Random();
     int integerIntered = Integer.parseInt(numberField.getText()); 
     return   random.nextInt(integerIntered - 0 + 1) + 0; 
}

Here is the Button

 bntGo.setText("Go");
    
    bntGo.setOnAction(e -> {
       randomIntegerField = String.valueOf(randomNum()); // The error i get is String can not converted into TextField. 
    });

Help me please

Solution

  • You need to set the text property of randomIntegerField (which I assume is a TextField), for example...

    bntGo.setOnAction(e -> {
       randomIntegerField.setText(String.valueOf(randomNum())); 
});
