It is used to call superclass methods, and to access the superclass constructor. The most common use of the super keyword is to eliminate the confusion between superclasses and subclasses that have methods with the same name.
Is superclass the parent class?Definitions: A class that is derived from another class is called a subclass (also a derived class, extended class, or child class). The class from which the subclass is derived is called a superclass (also a base class or a parent class).
What does super () do in Java?The super() in Java is a reference variable that is used to refer parent class constructors. super can be used to call parent class' variables and methods. super() can be used to call parent class' constructors only.
Which keyword lets you call the constructor of parent class?The super keyword is used to call the constructor of its parent class to access the parent's properties and methods.
