Question

I’ll let the code and errors do the talk, because I really think they say everything except THIS SHOULDN’T BE HAPPENING! Does anyone know how to make this compile?

Code

---

  class CountDownTimerGUI extends BHTimerGUI
  {
    private TimerJPanel control;
    private TimerDisplayJPanel disp;

    public CountDownTimerGUI(TimerJPanel control, TimerDisplayJPanel disp)
>>  {
      this.control = control;
      this.disp = disp;
    }
  }

(>>signifies the line of the error)

this overrides the constructor for BHTimerGUI, who’s constructor is as follows:

  public BHTimerGUI(TimerJPanel control, TimerDisplayJPanel disp)
  {
    this.control = control;
    this.disp = disp;
  }

Compiler Error

I:\Java\NetBeansProjects\Blue Husky's Timer 2.0.0\src\bhtimer\GUI.java:145: cannot find symbol
symbol  : constructor BHTimerGUI()
location: class bhtimer.BHTimerGUI
    {

NetBeans shows a popup with the following text:

constructor BHTimerGUI in class bhtimer.BHTimerGUI cannot be applied to given types;
  required: bhtimer.TimerJPanel,bhtimer.TimerDisplayJPanel
  found: no arguments
  reason: actual and formal argument lists differ in length

Answer 1

Yes, this SHOULD be happening! you are not initializing the superclass constructor.
Try with this constructor:

   public CountDownTimerGUI(TimerJPanel control, TimerDisplayJPanel disp){
      super(control, disp);
      this.control = control;
      this.disp = disp;
   }
