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

: 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. car-class-java

public class Car { // Attributes private String make; private String model; private int year; private double fuelLevel; private boolean isRunning; // Constructor public Car(String make, String model, int year) { this.make = make; this.model = model; this.year = year; this.fuelLevel = 100.0; // Starts with a full tank this.isRunning = false; } // Behavioral Methods public void startEngine() { if (fuelLevel > 0) { isRunning = true; System.out.println("The " + model + " engine roars to life."); } else { System.out.println("Out of fuel. Cannot start."); } } public void drive(double distance) { if (isRunning) { fuelLevel -= (distance * 0.05); // Simple fuel consumption logic System.out.println("Driving... Remaining fuel: " + fuelLevel + "%"); } else { System.out.println("Start the engine first!"); } } // Getters and Setters public String getModel() { return model; } public void setModel(String model) { this.model = model; } } Use code with caution.

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 ). IsRunning : A boolean flag to track the engine state

: String identifiers for the manufacturer and specific version. Year : An integer representing the production date.

The Car class is more than a coding drill; it is a demonstration of how real-world entities are modeled in software. By mastering encapsulation, state management, and class hierarchy, a developer builds a foundation for complex system architecture.

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
