Abstraction is a way of making complicated systems easier to understand by breaking them into smaller parts. Here are some examples from different industries that university students can relate to.
Think about building an app for renting cars.
Different types of vehicles like cars, trucks, and motorcycles have some things in common, like their brand, model, and color.
You could create a main class called Vehicle with actions like start(), stop(), and getDescription().
Then, each specific vehicle type could build on this main class, adding its special features while still using the basic actions.
Now, let’s look at a media player app that can play music and videos.
You might start with an abstract class called Media. This class would have a method called play().
Different media types, like Audio for music and Video for movies, would make their own versions of the play() method.
That way, you can easily use the same controls for all types of media.
In an online shopping site, there could be a main class called PaymentMethod with a method called processPayment().
Specific types of payments, like CreditCard and PayPal, would explain how to handle each payment type.
This way, users don’t have to worry about the complicated parts of making a payment.
These examples show how abstraction makes complex tasks simpler and helps developers reuse code in real-life applications.
