An abstract class: Is one from which you cannot create concrete objects, but from which you can inherit.
What is the use of super keyword?The super keyword refers to superclass (parent) objects. 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.
What is the use of super keyword in Java with example?3) super is used to invoke parent class constructor.
The super keyword can also be used to invoke the parent class constructor. Let's see a simple example: class Animal{ Animal(){System.out.println("animal is created");}
How to use super class in Java?Using Super to Access Superclass Constructor
You can learn more about Java constructors in our Java constructor tutorial here. To call a superclass constructor from a subclass constructor, we need to use super() inside the subclass constructor. Super() must be the first statement in the argument constructor.
