Question
Complete the Car class byDeclaring the String factory instance variableDeclaring the String model instance variableDeclaring int year instance variableDeclaring string colour instance variableWriting the constructor method with input parameters for factory, model, year and colourWriting the method carAge to display the age of the car (2024 - year)Complete the main method byUsing new to create an instance of Car with the constructor: Car("BMW" , "X5" , 2021 , "Black") Printing the car detailsPrinting the return value for the carAge() method on the Car instance
Solution
Here is the Java code that fulfills your requirements:
public class Car {
// Declare instance variables
String factory;
String model;
int year;
String colour;
// Constructor method with input parameters
public Car(String factory, String model, int year, String colour) {
this.factory = factory;
this.model = model;
this.year = year;
this.colour = colour;
}
// Method to calculate the age of the car
public int carAge() {
return 2024 - this.year;
}
// Method to print car details
public void printCarDetails() {
System.out.println("Factory: " + this.factory);
System.out.println("Model: " + this.model);
System.out.println("Year: " + this.year);
System.out.println("Colour: " + this.colour);
}
public static void main(String[] args) {
// Create an instance of Car
Car car = new Car("BMW", "X5", 2021, "Black");
// Print car details
car.printCarDetails();
// Print the age of the car
System.out.println("The age of the car is: " + car.carAge() + " years");
}
}
This code defines a Car class with the required instance variables and methods. The main method creates an instance of Car with the specified parameters, prints the car details, and then prints the age of the car.
