Question

This is a java program that runs on the Eclipse.

Java Programming 2-1: Java Class Design Interfaces Practice Activities Lesson objectives: Model business problems using Java classes Make classes immutable User Interfaces Vocabulary: Identify the vocabulary word for each definition below. A specialized method that creates an instance of a class. A keyword that qualifies a variable as a constant and prevents a method from being overridden in a subclass. A class that it can't be overridden by a subclass, in fact it can't be subclassed. Defines constants and methods without implementation Try it/Solve It: 1. Create an interface named Chassis. Add the following to the interface: A public constant string named chassis with a value of "Chassis". The definition of a public getChassis Type method that returns an instance of Chassis. The definition of a public setChassisType that accepts a string named vehicleChassis and returns a void. 2. Create an interface Engine with the following list of public method definitions that return a void: setEnginecylinders (int enginecylinders) setEngineManufacturedDate (Date date) setEngine Manufacturer (String manufacturer) set. EngineMake String engineMake setEngine Model (String engineModel); set DriveTrain (String driveTrain) setEngine Type (String fuel)

Answer 1

Vocabulary: Identify the vocabulary word for each definition below. Constructor final final class A specialized method that creates an instance of a class.

Hi, Since you have provided a question with 10 subparts, I am providing answer to first 4 subparts. For further subparts please ask seperately. Also if you find any difficulty in understanding any part of the code, feel free to comment.

Chassis.java

public interface Chassis {
    public final String chassis = "Chassis";
    public Chassis getChassisType();
    public void setChassisType(String vehicleChassis);
}

Engine.java

import java.util.Date;

public interface Engine {
    void setEngineCylinders(int engineCylinders);
    void setEngineManufacturedDate(Date date);
    void etEngineManufacturer(String manufacturer);
    void setEngineMake(String engineMake);
    void setEngineModel(String engineModel);
    void setDriveTrain(String driveTrain);
    void setEngineType(String fuel);
}

VehicleChassis.java

public class VehicleChassis implements Chassis{
    String chassisName;

    public VehicleChassis() {
        this.chassisName = chassis;
    }

    public VehicleChassis(String chassisName) {
        this.chassisName = chassisName;
    }

    @Override
    public Chassis getChassisType() {
        return new VehicleChassis();
    }

    @Override
    public void setChassisType(String vehicleChassis) {
        chassisName = vehicleChassis;
    }

    @Override
    public String toString() {
        return "Chassis Name : " + chassisName;
    }

    public static void main(String[] args){
        VehicleChassis vehicleChassis = new VehicleChassis();
        VehicleChassis vehicleChassis1 = new VehicleChassis("chasis name");
        System.out.println(vehicleChassis);
        System.out.println(vehicleChassis1);
    }
}

VehicleFrame.java

public class VehicleFrame implements Chassis{
    String vehicleFrameType;

    public VehicleFrame() {
        vehicleFrameType = "Unibody";
    }

    public VehicleFrame(String vehicleFrameType) {
        this.vehicleFrameType = vehicleFrameType;
    }

    @Override
    public Chassis getChassisType() {
        return new VehicleChassis();
    }

    @Override
    public void setChassisType(String vehicleChassis) {
        vehicleFrameType = vehicleChassis;
    }

    @Override
    public String toString() {
        return "Chassis : " + chassis + "\n" +
                "Vehicle Frame : " + vehicleFrameType;
    }

    public static void main(String[] args){
        VehicleFrame vehicleFrame = new VehicleFrame();
        System.out.println(vehicleFrame);
        vehicleFrame.setChassisType("Ladder Frame");
        System.out.println(vehicleFrame);
    }
}
