Software Architecture & Design $324$

Assignment$-3$:

You need to submit:

The entire Java code $($as Netbeans or Eclipse project$)$; if your code does not run regardless of

any reason, your grade is automatically zero.

Problem Description:

Based on your assigment$2$ solution, the requirement has changed so that the cruise controller is

missing part $$speed sensor$$ to control the speed of the shaft.

Therefore, the Cruise Control will now interact with the following hardware equipment:

$1)$ Cruise Control Handle $($with the ability to adjust speed and read product information$).$

$2)$ Brake $($with the ability to stop cruise and read product information$)$

$3)$ Engine $($with the ability to adjust Accelerator value and read product information$)$

$4)$ Speed Sensor $($with the ability to read product information$)$

$5)$ Accelerator $($with the ability to read product information$)$

Note: product information $=$ company name $+$ product name

As previously discussed in assignment$2,$ the vehicle company has agreed with a company called

$$Digital Car$$ company to manufacture the required hardware equipment. However, since

hardware development is expected to take longer than the expected software development,

management has decided to simulate the hardware components so that software development and

testing can move forward. That is$,$ there are two streams of equipment: real equipment $($from

Digital Car Company$)$ and the simulated equipment to allow the software development to go

forward.

Requirements:

$1)$ Design the creation of the required objects using the abstract factory design pattern so

that the Cruise Control software can work the same way using real or simulated

components. This design should be provided as UML class diagram. Note that you

should separate Digital Car company equipment from simulated equipment.

$2)$ Provide your Java implementation.

a$.$ The Java program should test the creation of all objects. Therefore, you need to

place the following line in each class constructor:

System.out.println$("$Created instance of class $"$

$+$this.getClass$().$getSimpleName$())$;

b$.$ The main method should test both the simulated and real hardware object

creations.
