Question

Using Java, have results display exactly like the SAMPLE OUTPUT at the bottom

Create the four classes as per the above UML diagram. Do NOT add any attributes or methods that don't appear in the UML diagrams. Don't modify anything, either. Create an executable class named TestVehicle test your work. In TestCollege, add code that accomplishes the tasks below. The sample output might assist you to understand these tasks.

In the main method of TestVehicle:

instantiate a Motor object for each vehicle you will code.

instances as follows:

make two objects with declared type Vehicle but actual type PassCar.

make at least one object of declared type Vehicle but actual type Truck.

make an array of type Object with the instances created above.

execute a void method named showVehicle (see below) with the Object array as sole argument.

create an Object Arraylist from the array already created. See page 439.

use a for loop to run through the ArrayList and display each object's data.

In the showVehicle method:

use a foreach loop to process the Object array.

for each Object, display the description method followed by the toString method. This will require
using the instanceof operator and casting.

SAMPLE OUTPUT

Output from the showVehicle method

In this application, a passenger car is an every day vehicle registered to an individual
make=Ford, model=Mustang, year=2016, price=44500.0
PassCar numPass=5, AC=true
Motor EcoBoost, cylinders=6, bhp=310, displacement=2.3

In this application, a Truck is a vehicle designed to transport cargo
make=Dodge, model=Ram, year=2016, price=46000.0
Truck type=pickup, capacity=1500
Motor Hemi, cylinders=8, bhp=707, displacement=5.7

In this application, a passenger car is an every day vehicle registered to an individual
make=Tesla, model=Model S, year=2016, price=121000.0
PassCar numPass=2, AC=true
Motor P90D, cylinders=0, bhp=762, displacement=0.0

Output from ArrayList in main

make=Ford, model=Mustang, year=2016, price=44500.0
PassCar numPass=5, AC=true
Motor EcoBoost, cylinders=6, bhp=310, displacement=2.3

make=Dodge, model=Ram, year=2016, price=46000.0
Truck type=pickup, capacity=1500
Motor Hemi, cylinders=8, bhp=707, displacement=5.7

make=Tesla, model=Model S, year=2016, price=121000.0
PassCar numPass=2, AC=true
Motor P90D, cylinders=0, bhp=762, displacement=0.
