Question

I am making a seat monitoring system using java PL. I have this method in my ComputerSeats class:

public void occupySeat()
{
    seatOccupied[station-1] = true;
    mtr.showArrayIdVal().setText(stud.showField().getText());
    seat[station-1].setBackground(Color.red);
    occupiedSeatCounter++;
}

the ShowArrayIdVal contains a Jlabel[] object, the value of this label is “Vacant Station”, I used setText(stud.showField().getText()) to change “Vacant Station” to the value that I have inputted using JTextField. But then, whenever I compile it, It contains an error which states that it cannot find settext().

Answer 1

If mtr.showArrayIdVal() is returning a JLabel Object your code should work fine.

I assume that mtr.showarrayidval() is returning array of Jlable objects. so, you should be getting the object on the index and then call setText(...).

   for(JLable jl: mtr.showArrayIdVal()) {
        jl.setText(..)// do what ever you are setting here.
     }
