Only the parent class constructor can be referenced and cannot be called.             A reference can only appear in the first row of the constructor. * Super refers to the parent class's constructor instead of the parent class's property, and if you make the parent class's construction method private you can see that the subclass's construct with super is wrong. Because super calls the constructor of the parent class *, so in the parent class constructor The this represents the parent class, the assigned attribute is also the parent class, where the sense of inheritance in the subclass is a mapping of the parent class property, because it is affected by the modifier * words in the parent class.
