From Requirements to Classes

From Requirements to Classes

In What Does OOP Mean? Intro to Object Oriented Programming, we learned the core mental model: objects have properties and methods, and classes act like blueprints for those objects.

Now we need the next practical skill: given a plain English requirement, how do we decide what classes to write?

This matters in real software engineering and in OOP interview rounds. You may hear something like:

Design a simple study tracker for coding challenges.

A strong answer starts by translating that sentence into:

• class names
• fields
• methods
• object responsibilities

We are not designing a giant system yet. We are learning the first move: turning requirements into small, usable Java classes.
