A "solid" Car class often serves as a parent class. Through , we can create specialized classes like ElectricCar or Truck that inherit the properties of Car but add specific features (e.g., batteryCapacity or towingLimit ).
In Java, a class acts as a blueprint. A Car class encapsulates the data (state) and methods (behavior) that define what a car is and what it can do within a software system. This structure allows developers to create multiple "instances" (individual cars) with unique properties while sharing the same underlying logic. 2. Core Attributes and Encapsulation
: String identifiers for the manufacturer and specific version. Year : An integer representing the production date.
: A double representing the current gas or charge. IsRunning : A boolean flag to track the engine state. 3. Implementation Example Below is a standard implementation of a robust Car class.
allows us to treat a List containing both gas and electric vehicles uniformly, calling a .refuel() method that behaves differently depending on the specific object type. 5. Conclusion
The state of a car is defined by its fields. To follow Java best practices, we use by marking these fields private and providing public getter and setter methods. This protects the data from unauthorized interference.
This paper explores the implementation and design philosophy of a Car class in Java, a fundamental exercise in Object-Oriented Programming (OOP). We will cover the core components: encapsulation of attributes, constructor logic, and behavioral methods. 1. Introduction to the Car Class
