How to make a parameter list that accepts multiple values as arguments

I am not sure wether I formulated the question well. I have a problem. I created a class that provides my window (javafx Pane) with a row of buttons from top to down. Now I want to have the same with textfields. But I just don't know how to manage it without have to copy and paste the whole code to overload a second or third constructor again and again just to change a button for a label or a textfield. Has anyone an idea how to make it work, that my code stays compact. Thank you in advance. Here the code.

public class ArrBtn {

private ArrayList<Button>       arrBtn      = new ArrayList<Button>();

private int     index;
private double  setX; 


    ArrBtn (int arraySize, Pane root ) {                                  //     It ads itself by itself by giving the reference of the Pane.               

        double distX = 60;                                                // Sets the distance in x-direction between the buttons.

        for (int i = 0; i < arraySize -1; i++) {

        arrBtn.get(index).setLayoutX        (30 +setX*distX);             // Sets the x-position of the Buttons.
        arrBtn.get(index).setLayoutY        (30            );             //     Sets the y-position of the Buttons.
        arrBtn.get(index).setPrefWidth      (40            );             //     Sets the width of the Buttons.
        arrBtn.get(index).prefHeight        (40            );             //     Sets the height of the Buttons.
        index++;

            setX++;                                                       //         Makes the next button is set on another x-position.
        }
    }
}
