java - 编译器无法正确识别构造函数重写

Question

我会让代码和错误来说话，因为我真的认为他们说了一切，除了这不应该发生!有人知道如何编译这个吗？

代码

<小时/>

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

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

(>>表示错误行)

这会覆盖 BHTimerGUI 的构造函数，其构造函数如下:

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

编译器错误

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 显示一个包含以下文本的弹出窗口:

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

是的，这应该发生!您没有初始化父类(super class)构造函数。尝试使用这个构造函数:

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