inheritance Basics: Recipe Extension

Learning Objective: Add fields to parent class with inheritance and extend functionality

In this problem, you will create a program that implements a Recipe parent class and a SpecialRecipe child class, where each class's getTypeName() method returns "Regular recipe" or "Special recipe" and displays the result to standard output.

Create SpecialRecipe class inheriting from Recipe class. Learn how to add child class unique fields in addition to parent class functionality.

Understanding with Concrete Examples

Example 1: Regular Recipe (Parent Class)

Input: new Recipe("Pasta", 15)
Output: Regular recipe

Example 2: Special Recipe (Child Class)

Input: new SpecialRecipe("Truffle Pasta", 15, "Truffle")
Output: Special recipe
(Explanation: Special pasta using truffle)

Example 3: Special Even if Quick (Boundary)

Input: new SpecialRecipe("Caviar Pasta", 10, "Caviar")
Output: Special recipe
(Explanation: Special recipe with caviar even in 10 minutes)
