Question

write the following programs: Ram.java, Truck.java, LandVehicle.java and Vehicle.java.

public class Ram extends Truck { public static void main(String[] args) {

    // your implementation
  }

  public Ram() {
    // your implementation

} }

public class Truck extends LandVehicle {
  public Truck() {

    // your implementation
  }

  public Truck(String s) {
    // your implementation

} }

public class LandVehicle extends Vehicle {
  public LandVehicle() {

    // your implementation
  }

}

public class Vehicle {
  public Vehicle() {

    // your implementation

Answer 1

You did not tell what should be implemented, so built a basic functional program for the above classes.

Ram.java

public class Ram extends Truck {
      public Ram(String s) {
       super(s);
       // TODO Auto-generated constructor stub
   }

   public static void main(String args[]){
          Vehicle v=new Vehicle();
          v.drive();
          LandVehicle lv = new LandVehicle();
          lv.LandDrive();
          lv.drive();
          Truck t = new Truck("Hello");
      
          Ram r = new Ram("Ram");
          r.drive();
          r.LandDrive();
      
}
}

Truck.java

public class Truck extends LandVehicle {

public Truck(String s) {
      System.out.println("Truck Driving " +s);
} }

LandVehicle.java

public class LandVehicle extends Vehicle {
public void LandDrive() {
      System.out.println("Land Driving");
    // your implementation
}

}

Vehicle.java

public class Vehicle {
public void drive() {
       System.out.println("Driving");
    // your implementation
}
}
