REST API Automation Testing from Scratch - REST Assured Java - Using Inheritance in JAVA

The video tutorial explains the concept of inheritance in Java programming. It begins with an introduction to inheritance, followed by a practical example using a vehicle to demonstrate how inheritance allows for code reuse. The tutorial distinguishes between inheritance and interfaces, highlighting their differences. It then provides a step-by-step guide on implementing a parent class and using the 'extends' keyword to inherit properties and methods in a child class. The tutorial emphasizes the benefits of inheritance, such as code reusability and efficiency.

What is the primary benefit of using inheritance in Java?

• To create more classes

• To write more code

• To reuse existing code

• To avoid using interfaces

In the vehicle example, what is the purpose of the parent class?

• To implement interfaces

• To reuse existing code for gears and brakes

• To provide a template for new vehicles

• To define new features

How does inheritance differ from interfaces in Java?

• Interfaces allow code reuse, inheritance does not

• Inheritance allows code reuse, interfaces do not

• Neither inheritance nor interfaces allow code reuse

• Both inheritance and interfaces allow code reuse

In the context of inheritance, what does the term 'reusable' refer to?

• Implementing new interfaces

• Creating new classes

• Writing new code

• Using existing code without modification

Which of the following is a basic property defined in the parent class example?

• Wheels

• Windows

• Color

• Seats

What is the significance of defining methods in the parent class?

• To create new methods

• To avoid writing code in the child class

• To ensure methods are not inherited

• To make the class abstract

What is the role of the 'extends' keyword in Java?

• To define a method

• To inherit properties from a parent class

• To create a new class

• To implement an interface

What happens if you remove the 'extends' keyword from a child class?

• The child class will throw an error

• The child class will still inherit properties

• The child class will become an interface

• The child class will not inherit properties

What is the output when accessing the 'color' property in the child class?

• Blue

• Green

• Red

• Yellow

Which keyword is used to implement an interface in Java?

• extends

• implements

• inherits

• uses
