Develop a Java Application with ‘Vehicle’ Class with vehicle type, vehicle number, as member. Inherit the classes bicycle, car, bike, and lorry from vehicle class. Consider car and bike only as passenger vehicle. Get inputs engine number, chassis number, top speed, number of passengers, number of gears for Passenger vehicle, and if is not a passenger vehicle, get inputs total amount of load to carry for the respective inherited classes. Generate a report for the vehicles. Implement the concept using inheritance and method overriding.

Solution 1

Sure, here is a simple implementation of the problem in Java:

// Vehicle class
public class Vehicle {
    String vehicleType;
    String vehicleNumber;

    public Vehicle(String vehicleType, String vehicleNumber) {
        this.vehicleType = vehicleType;
        this.vehicleNumber = vehicleNumber;
    }

    public void report() {
        System.out.println("Vehicle Type: " + vehicleType);
        System.out.println("Vehicle Number: " + vehicleNumber);
    }
}

// PassengerVehicle class
public class PassengerVehicle extends Vehicle {
    String engineNumber;
    String chassisNumber;
    int topSpeed;
    int numberOfPassengers;
    int numberOfGears;

    public PassengerVehicle(String vehicleType, String vehicleNumber, String engineNumber, String chassisNumber, int topSpeed, int numberOfPassengers, int numberOfGears) {
        super(vehicleType, vehicleNumber);
        this.engineNumber = engineNumber;
        this.chassisNumber = chassisNumber;
        this.topSpeed = topSpeed;
        this.numberOfPassengers = numberOfPassengers;
        this.numberOfGears = numberOfGears;
    }

    @Override
    public void report() {
        super.report();
        System.out.println("Engine Number: " + engineNumber);
        System.out.println("Chassis Number: " + chassisNumber);
        System.out.println("Top Speed: " + topSpeed);
        System.out.println("Number of Passengers: " + numberOfPassengers);
        System.out.println("Number of Gears: " + numberOfGears);
    }
}

// NonPassengerVehicle class
public class NonPassengerVehicle extends Vehicle {
    int totalLoad;

    public NonPassengerVehicle(String vehicleType, String vehicleNumber, int totalLoad) {
        super(vehicleType, vehicleNumber);
        this.totalLoad = totalLoad;
    }

    @Override
    public void report() {
        super.report();
        System.out.println("Total Load: " + totalLoad);
    }
}

In this code, Vehicle is the parent class with vehicleType and vehicleNumber as members. PassengerVehicle and NonPassengerVehicle are child classes that inherit from Vehicle. PassengerVehicle has additional members like engineNumber, chassisNumber, topSpeed, numberOfPassengers, and numberOfGears. NonPassengerVehicle has an additional member totalLoad. The report method is overridden in both child classes to print the details of the vehicle.

Sure, here is a simple implementation of the problem in Java:

// Vehicle class
public class Vehicle {
    String vehicleType;
    String vehicleNumber;

    public Vehicle(String vehicleType, String vehicleNumber) {
        this.vehicleType = vehicleType;
        this.vehicleNumber = vehicleNumber;
    }

    public void report() {
        System.out.println("Vehicle Type: " + vehicleType);
        System.out.println("Vehicle Number: " + vehicleNumber);
    }
}

// PassengerVehicle class
public class PassengerVehicle extends Vehicle {
    String engineNumber;
    String chassisNumber;
    int topSpeed;
    int numberOfPassengers;
    int numberOfGears;

    public PassengerVehicle(String vehicleType, String vehicleNumber, String engineNumber, String chassisNumber, int topSpeed, int numberOfPassengers, int numberOfGears) {
        super(vehicleType, vehicleNumber);
        this.engineNumber = engineNumber;
        this.chassisNumber = chassisNumber;
        this.topSpeed = topSpeed;
        this.numberOfPassengers = numberOfPassengers;
        this.numberOfGears = numberOfGears;
    }

    @Override
    public void report() {
        super.report();
        System.out.println("Engine Number: " + engineNumber);
        System.out.println("Chassis Number: " + chassisNumber);
        System.out.println("Top Speed: " + topSpeed);
        System.out.println("Number of Passengers: " + numberOfPassengers);
        System.out.println("Number of Gears: " + numberOfGears);
    }
}

// NonPassengerVehicle class
public class NonPassengerVehicle extends Vehicle {
    int totalLoad;

    public NonPassengerVehicle(String vehicleType, String vehicleNumber, int totalLoad) {
        super(vehicleType, vehicleNumber);
        this.totalLoad = totalLoad;
    }

    @Override
    public void report() {
        super.report();
        System.out.println("Total Load: " + totalLoad);
    }
}

You can create instances of PassengerVehicle and NonPassengerVehicle for car, bike, bicycle, and lorry as per your requirements.

Sure, here is a simple implementation of the problem in Java:

// Vehicle class
public class Vehicle {
    String vehicleType;
    String vehicleNumber;

    public Vehicle(String vehicleType, String vehicleNumber) {
        this.vehicleType = vehicleType;
        this.vehicleNumber = vehicleNumber;
    }
}

// PassengerVehicle class
public class PassengerVehicle extends Vehicle {
    String engineNumber;
    String chassisNumber;
    int topSpeed;
    int numberOfPassengers;
    int numberOfGears;

    public PassengerVehicle(String vehicleType, String vehicleNumber, String engineNumber, String chassisNumber, int topSpeed, int numberOfPassengers, int numberOfGears) {
        super(vehicleType, vehicleNumber);
        this.engineNumber = engineNumber;
        this.chassisNumber = chassisNumber;
        this.topSpeed = topSpeed;
        this.numberOfPassengers = numberOfPassengers;
        this.numberOfGears = numberOfGears;
    }
}

// NonPassengerVehicle class
public class NonPassengerVehicle extends Vehicle {
    int totalLoad;

    public NonPassengerVehicle(String vehicleType, String vehicleNumber, int totalLoad) {
        super(vehicleType, vehicleNumber);
        this.totalLoad = totalLoad;
    }
}

// Car class
public class Car extends PassengerVehicle {
    public Car(String vehicleNumber, String engineNumber, String chassisNumber, int topSpeed, int numberOfPassengers, int numberOfGears) {
        super("Car", vehicleNumber, engineNumber, chassisNumber, topSpeed, numberOfPassengers, numberOfGears);
    }
}

// Bike class
public class Bike extends PassengerVehicle {
    public Bike(String vehicleNumber, String engineNumber, String chassisNumber, int topSpeed, int numberOfPassengers, int numberOfGears) {
        super("Bike", vehicleNumber, engineNumber, chassisNumber, topSpeed, numberOfPassengers, numberOfGears);
    }
}

// Lorry class
public class Lorry extends NonPassengerVehicle {
    public Lorry(String vehicleNumber, int totalLoad) {
        super("Lorry", vehicleNumber, totalLoad);
    }
}

// Bicycle class
public class Bicycle extends NonPassengerVehicle {
    public Bicycle(String vehicleNumber, int totalLoad) {
        super("Bicycle", vehicleNumber, totalLoad);
    }
}

In this code, we have a base class Vehicle with vehicleType and vehicleNumber as members. We then have two classes PassengerVehicle and NonPassengerVehicle that extend Vehicle and add their own members. Finally, we have Car, Bike, Lorry, and Bicycle classes that extend PassengerVehicle or NonPassengerVehicle and set the vehicleType in their constructors.

You can create instances of these classes and use their members to generate a report for the vehicles.
