What is the concept of inheritance in Java?
Inheritance in Java is a concept that acquires the properties from one class to other classes; for example, the relationship between father and son. In Java, a class can inherit attributes and methods from another class. The class that inherits the properties is known as the sub-class or the child class.
How can you define a class that inherits from another class and uses the parent class’s constructor?
From the derived class, you can use super from any constructor or method to access its base class:
- To call the parent constructor, use super().
- To call another member, use, for example, super. getName() .
How does prototypal inheritance work and how is it different from classical inheritance?
The difference between classical inheritance and prototypal inheritance is that classical inheritance is limited to classes inheriting from other classes while prototypal inheritance supports the cloning of any object using an object linking mechanism.
