Really don't understand what you said is what, subclass when initialized automatically calls the superclass constructor, the constructor is used during initialization,

CodePudding user response:

 
Public class Student {
A String of major; 

Public Student () {
super();//call the superclass constructor 
} 

}

In addition, the parent class structure can't call a subclass constructor,
There is only one parent, but subclasses may have multiple,

Not parent can't call a subclass constructor, was once called subclass will automatically call the superclass constructor again, this becomes infinite loop dolls,
