can anyone give me example ,i seem to struggle with understanding Object Oriented Programming . pening lalat woo

ChatGPT Gemini can help

thx !!!

everyone learning preference are different.

some people may need to do a lot of practice, from the code and result to understand the concept,

some other need to understand the concept, then start to read / code to understand how to make it work.

in short, either read a lot, or type a lot, or both.

What book are you reading to learn OOP? And which programming language?

Look for the example of the 4 principles of OOP in the language u understand, it's hard to understand the essence by just reading the theory

Think of raw construction materials, like wood, sand or rocks. Used as-is, we can maybe whip up a basic shelter like a hut.

Take some sand, cement, water and pour it into a rectangular mould. We've Encapsulated those materials into a standard unit, a brick.

The shape and size of the brick is independent from the material it is made of. The brick is an Abstraction. Now we can make straight, tall walls for a house.

Perhaps the sand brick is too weak to build over a certain height, or looks ugly. Mix in some stone, or use clay, but keep the same mould dimensions. The new bricks Inherit the dimensions of the original brick but have different properties such as strength, or may be more expensive (or cheaper).

Because the dimensions of the brick are the same we can use the bricks interchangeably to achieve the desired strength, aesthetics, or cost target for our wall. They exhibit Polymorphism.

Now, recall the usual programming 101 material such as variables, functions, if-else statements, for-loops, whiles or do-whiles, etc. Those are the raw materials that we use as programmers.

Exactly what is it about OOP that you find it hard to understand?

Sometimes it easier to understand if you start to implement what you read/learn. Try to develop a simple projects such as daily journal or some calculation related projects. Use those Ai to guide you through this process. Then try to implement what you learned earlier.

Great example

the simple example to easy understand.

proton car.

car is class and proton is object.

Almost. You could say that, "A red Proton Saga with half a tank of petrol, 79000 km on the odometer, half-worn GoodYear tyres, going at 90km/h on the PLUS highway", is an object of the Car class.
