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);     } } 

Sample Output : VehicleChassis.java

Sample Output : VehicleFrame.java

Hope it helps!
