When new programmers start learning object-oriented programming (OOP) and working with classes, they often make some common mistakes. By staying away from these errors, you can write cleaner and better code.
Not Knowing What Classes Are For: Classes are like blueprints for creating objects. They hold data and the actions (methods) you can do with that data. Think of a class as a plan for building a house. Without the plan, you can’t build your house (or object).
Skipping Constructors: A constructor is a special method used to set up an object when it’s created. If you forget to use constructors, your objects might not be ready to use. Always make sure to set up your object’s details first!
Using Global Variables Too Much: New programmers sometimes use global variables, thinking it makes coding easier. But this can cause problems with your data and make it harder to fix any bugs. It’s better to keep your data inside classes.
Not Using Inheritance Wisely: OOP lets you create new classes based on existing ones, which helps you reuse code. If you don’t use inheritance, you might end up writing the same code more than once.
By avoiding these common mistakes, you’ll be able to write strong and easy-to-manage object-oriented code!
