Question

i need this in java code and wiht comments thanks

You are give the following interface Movable: public interface Movable public void move forward(); public void move Backward(); public void stop(); public void moveLeft() public void moveRight(); ) Base on the Movable interface create three classes: Caro), Plane(), and Ship that implement it. After that, create a program that will polymorphically process an array of Movable by calling each of the interface methods, after creating an object for each one of the classes. Implement the classes in such a way that the output is: Plane flying forward Plane taxiing backward Plane landed Plane flying left Plane flying right Cat drives forward Cat drives backward Car parked Car turn left Car turns right Ship navigates forward Ship navigates backward Ship docked Ship navigates left Ship navigates right

Java Code

//interface
interface Movable{
public void moveForward();
public void moveBackward();
public void stop();
public void moveLeft();
public void moveRight();
}
//class Car implements interface
class Car implements Movable
{ //Implementing functions of interface
public void moveForward() //Code for moveForward method of interface
{
System.out.println("Car drives forward"); //print
}
public void moveBackward() //Code for moveBackward method of interface
{
System.out.println("Car drives backward"); //print
}
public void stop() //Code for stop method of interface
{
System.out.println("Car parked"); //print
}
public void moveLeft() //Code for moveLeft method of interface
{
System.out.println("Car turns left"); //print
}
public void moveRight() //Code for moveRight method of interface
{
System.out.println("Car turns right"); //print
}
}
//class Plane implements interface
class Plane implements Movable
{ //Implementing functions of interface
public void moveForward() //Code for moveForward method of interface
{
System.out.println("Plane flying forward"); //print
}
public void moveBackward() //Code for moveBackward method of interface
{
System.out.println("Plane taxiing backward"); //print
}
public void stop() //Code for stop method of interface
{
System.out.println("Plane landed"); //print
}
public void moveLeft() //Code for moveLeft method of interface
{
System.out.println("Plane flying left"); //print
}
public void moveRight() //Code for moveRight method of interface
{
System.out.println("Plane flying right"); //print
}
}
//class Ship implements interface
class Ship implements Movable
{ //Implementing functions of interface
public void moveForward() //Code for moveForward method of interface
{
System.out.println("Ship navigates forward"); //print
}
public void moveBackward() //Code for moveBackward method of interface
{
System.out.println("Ship navigates backward"); //print
}
public void stop() //Code for stop method of interface
{
System.out.println("Ship docked"); //print
}
public void moveLeft() //Code for moveLeft method of interface
{
System.out.println("Ship navigates left"); //print
}
public void moveRight() //Code for moveRight method of interface
{
System.out.println("Ship navigates right"); //print
}
}
  
public class Main
{
   public static void main(String[] args) {
   Movable mov[] = {new Plane(), new Car(), new Ship()}; //Creating array of Movable interface which contains the object of all the classes.
   for(int i =0; i<mov.length; i++)
   { //Plane object will call all interface methods when i =0
   //Car object will call all interface methods when i =1
   //Ship object will call all interface methods when i =2
   mov[i].moveForward();
   mov[i].moveBackward();
   mov[i].stop();
   mov[i].moveLeft();
   mov[i].moveRight();
   System.out.println("-----------------------");
   }
   }
}

Output

Plane flying forward Plane taxiing backward Plane landed Plane flying left Plane flying right Car drives forward Car drives backward Car parked Car turns left Car turns right Ship navigates forward Ship navigates backward Ship docked Ship navigates left Ship navigates right
