Class
In short
A class is a blueprint used in programming to create objects that share the same properties and behaviours.
In plain words
Think of it as a set of instructions or a template. It defines what data an object will hold and what actions it can perform.
A simple example
A blueprint for a car is a class. The actual physical cars parked in your driveway are the objects built from that blueprint.
Why it matters
It allows programmers to organise code efficiently and reuse logic. Instead of writing new code for every single item, you just create new instances of a class.
Easy to mix up
People often confuse a class with an object; the class is the plan, while the object is the actual thing.
