Constructors are not inherited . The superclass constructor can be called from the first line of a subclass constructor by using the keyword super and passing appropriate parameters to set the private instance variables of the superclass.
Read moreCan a class inherit the constructor of its superclass Why?
No a subclass cannot inherit the constructors of its superclass . Constructors are special function members of a class in that they are not inherited by the subclass.
Read moreDoes a subclass constructor need to use super?
It is required if the parameterized constructor (a constructor that takes arguments) of the superclass has to be called from the subclass constructor . The parameterized super() must always be the first statement in the body of the constructor of the subclass, otherwise, we get a compilation error.
Read moreDo subclasses need super?
You need a call to super() if and only if there’s no default constructor (accepting no arguments) for your parent class . In all other cases (where a constructor with zero arguments exists) you don#t have to code it.
Read moreWhat happens if you do not call super () in the subclass constructor?
If a constructor does not explicitly invoke a superclass constructor, the Java compiler automatically inserts a call to the no-argument constructor of the superclass . If the superclass does not have a no-argument constructor, you will get a compile-time error.
