In Object-Oriented Programming (OOP), we have two important parts called properties and methods. These parts help classes work better and do more things.
Properties are like the traits or features of a class. They keep track of important information about an object. Think of a class named Car. The properties of this class could include things like color, make, model, and year. Each of these properties gives us details about the car. This way, we can create different car objects in our program that represent real cars.
On the other hand, methods are the actions that can be done with a class. They show what you can do with the information stored in the properties. Using our Car example again, methods might include start(), stop(), or accelerate(). Each method does something with the car's properties. For instance, when we use the start() method, we might change a property called isRunning to true, which means the car has started. Clearly separating properties and methods helps make the code easier to read and work with.
Another cool thing about OOP is encapsulation. This means we can keep properties private or protected, which helps keep our data safe. When properties are not accessible from outside the class, we can control how they get changed. For example, instead of letting someone directly change a speed property, we could create a method called setSpeed(value). This method can check to make sure the speed is always a positive number, keeping our Car object safe.
OOP also lets us create more organized models using inheritance and polymorphism. Inheritance means we can create a new class based on another class, which helps us reuse code. For example, we could have a base class called Vehicle that has properties like color and type, along with methods like drive() or brake(). When Car inherits from Vehicle, it can use these shared properties and methods but also add its own special features.
Interfaces and abstract classes take this idea even further. They let different classes use the same methods but in different ways. This makes it easier to develop complex systems without having to redesign everything. For instance, both a Car and a Bicycle could use an interface called Drivable, which means both must have a drive() method. Because of this, we can call drive() on any Drivable object, no matter what type it is. This is called polymorphism, and it makes our designs more flexible.
In summary, properties and methods are key parts that make classes work well in OOP. They help define what an object is like and what it can do. They ensure our data remains safe, support code reuse through inheritance and interfaces, and allow for flexible design with polymorphism. By using these important pieces, we can create strong and adaptable software that represents real-world situations effectively.
