Recap: Vehicle Fleet

Combine inheritance, overriding methods, polymorphism, and abstract classes

Mission: Tommy's Fleet

Tommy has a mixed fleet in his Vice City garages: sports cars, trucks, motorcycles. Each type burns fuel at a different rate. Build an abstract Vehicle system so the whole fleet can be managed the same way, no matter the type.

Create an abstract class Vehicle with:

• Fields: name (String), fuel (int, starts at 100)
• Constructor takes the name
• abstract String type(): each subclass returns its type
• abstract int fuelPerKm(): fuel burned per km (different for each vehicle)
• void drive(int km): reduces fuel by km * fuelPerKm(). If there isn't enough fuel, print "Not enough fuel!" and change nothing
• toString(): returns "name (type) - Fuel: X%"

Then create three concrete subclasses:

• SportsCar: fuelPerKm() returns 2, type() returns "SportsCar"
• Truck: fuelPerKm() returns 5, type() returns "Truck"
• Motorcycle: fuelPerKm() returns 1, type() returns "Motorcycle"

In main, store the three vehicle names in name1, name2, name3 and the four driving distances in km1, km2, km3, km4. Put a SportsCar (from name1), a Truck (from name2), and a Motorcycle (from name3) in a Vehicle[] array, then drive: the first vehicle km1, the second km2, the second again km3, and the third km4. Finally print each one. The distances are chosen so the second vehicle's second drive can force a "Not enough fuel!".

Example

With a SportsCar "Infernus" driven 15 km, a Truck "Linerunner" driven 15 km and then another 20 km (not enough left: 20*5 = 100 > 25), and a Motorcycle "Angel" driven 15 km, you'd get:

Not enough fuel!
Infernus (SportsCar) - Fuel: 70%
Linerunner (Truck) - Fuel: 25%
Angel (Motorcycle) - Fuel: 85%
