Design Pattern - Strategy

Strategy is a behavioral design pattern that lets you define a family of algorithms, put each of them into a separate class, and make their objects interchangeable. This pattern suggests that you take a class that does something specific in a lot of different ways and extract all of these algorithms into separate classes called strategies.

This repository contains two assignments done in Strategy pattern:

• Numbers
• Operations

Numbers 🔢

The task was to create classes, which will encapsulate different ways of displaying an int number in output:

• decimal,
• binary,
• hexadecimal.

Operations ➕➖✖️➗

The task was to create classes, which will encapsulate different math operations with two int numbers:

• addition,
• substracton,
• multiplication,
• division.
