What is object oriented programming in computer science?
In computer science, object oriented programming refers to organising code around objects that bundle data with the behaviour acting on it. It matters because the same idea reappears across many later topics, so building a clear mental picture of it early saves a lot of time.
How to approach it step by step
To work with object oriented programming confidently, identify entities, give them attributes and methods, then use inheritance for shared behaviour. LetMeTeach draws this out live on screen while explaining it aloud, so you watch each part appear instead of decoding a static block of text. You can interrupt at any point and ask for the same idea again in simpler words, in another language, or with a different example.
Worked example
A Car class can extend a Vehicle class and reuse its start method.
The mistake most learners make
Using inheritance where composition would describe the relationship better.
