Question

This project has 3 classes which are already defined for you. Do not change any of these:
- Vehicle: an abstract class for any make and model of vehicle that can possibly travel some distance.
- LimitedRange: an interface for something that has a limit to the distance it can travel.
- Main: a test program which will work after you have written the code below.
Your job is to write the following 3 classes so that this program produces the sample output shown at the end of Main. Specifically you will need:
- ElectricCar: a vehicle with a limited range. So it must be a subclass of Vehicle, and it must implement LimitedRange. Thus it needs an instance variable for its range, and a travel method (required by Vehicle. Please use @Override) that outputs "Zoom!" if it has enough range to go the distance specified (and update its range). It must have a constructor with 3 arguments as called by main. (Remember that the first line of the constructor must be a call to "super": Vehicle's constructor specifying the make and model.) It also needs a getCurrentRange method as required by LimitedRange (use @Override for this too).
- Motorboat: a vehicle with a limited range. So it is similar to ElectricCar, but it outputs "Wisshhh!" when it goes.
- Sailboat: a vehicle that doesn't have a limited range. So it is a subclass of Vehicle, but doesn't implement LimitedRange. It can go any distance, and outputs "Weee!" when it travels.

DO NOT CHANGE THIS CODE

class Main

{

publicstaticvoid main(String[] args)

{

Vehicle[] vehicles = new Vehicle[3];

vehicles[0] = new ElectricCar("Tesla", "Model 3", 262);

// 262 mile range

vehicles[1] = new Motorboat("Starweld", "16 Fusion DC", 45);

// 45 mile range

vehicles[2] = new Sailboat("Gulf Marine", "Gulf 32");

// sailboats have unlimited range

for(Vehicle v : vehicles)

{

goDistanceTest(v, 20);

goDistanceTest(v, 40);

System.out.println();

}

// Test v to see if it can go distance, and output results.

staticvoid goDistanceTest(Vehicle v, int distance)

{

System.out.print("Going " + distance + " miles: ");

if (!v.travel(distance))

System.out.println("Can't make it.");

elseif(v instanceof LimitedRange)

{

System.out.println("I can go " + ((LimitedRange)v).getCurrentRange() + " miles farther.");

}

/* Sample Output that you should get after you write

ElectricCar.java, Motorboat.java, and Sailboat.java:

Going 20 miles: Zoom!

I can go 242 miles farther.

Going 40 miles: Zoom!

I can go 202 miles farther.

Going 20 miles: Wisshhh!

I can go 25 miles farther.

Going 40 miles: Can't make it.

Going 20 miles: Weee!

Going 40 miles: Weee!
