super调用的是父类的构造方法，你父类的构造函数什么都没有，没有意义。
super的使用：直接super就是了，当然也可以往里面传入参数。

Director(String name,String position,String address,double transportAllowance)
{
  this.name = name;
  this.position = position;
  this.address = address;
  this.transportAllowance = transportAllowance;

//听 说这里可以用super();代替。但是这个super()到底是怎么来的？怎么代入进去的？求解！
}
完全没希望，你听错了吧，应该是构造函数第一行有个隐式的super()把

super即是父类的引用，
super（）；即是引用父类无参构造函数。
super(参数);即是引用带参构造方法
一般用给本类进行初始化
