Object-oriented design

Object-oriented design is a way of organizing information so it is easier to understand and interact with. Think of it like a house. A house has lots of different parts, like walls, windows, doors, and floors. Each part does something different, and they all work together. Object-oriented design is like building a house, but instead of walls and windows, you're building objects and classes. An object is like a window - it has characteristics (like size, shape, and color) and it can do something (like open or close). A class is like the blueprint of something - it tells you how to build the window, how it should look and behave. By combining multiple objects and classes, you can create larger, more complex systems that do lots of things.
