Assignment #$5$: Structural and Behavioral Design Patterns $[4\%]$

This assignment relates to the following Course Learning Requirements:

CLR $1-$ Implement an objected$-$oriented program design incorporating the use of best practice design patterns using the JAVA programming language.

Part I:

Proxy Pattern

The current code includes two classes that represent the APIs for Google and AWS services, but only a subset of the methods implemented are required for application. Because we want to expose the application only, the methods that are really required are as follows:

$1.$ Implement a Proxy named GoogleSpeech$2$TextProxy for the Google API

$2.$ Implement a Proxy named AWSTranscribeProxy for the AWS API.

$3.$ Update the CCWorker class accordingly.

Adapter Pattern

We want to make use of the same interface $($therefor$,$ the same method$)$ for accessing the two Proxies.

$1.$ Implement a CCGoogleAdapter and CCAWSAdapter that have the same method $($although different logic$)$ for triggering the closed$-$captioning process.

$2.$ Update the CCWorker class accordingly $($keep the cc triggering using local methods$).$

Part II:

Observer Pattern

We want to have notifications that can be sent to the Console to simulate an external Event Logging System that may be used for Analytics and Live Monitoring.

$1.$ Implement Observer pattern being the Recording class, the Observable Subject, and a new Notifier class, the Observer.

$2.$ The event should be triggered when the Recording is updated with the transcript $($or result from the closed captioning process$)$ and the message generated should include information from the recording itself.

$3.$ Update the Main class accordingly.

Submission:

Your submission for this assignment should include:

$1.$ Java code of your final solution.

$2.$ Report of your observations on the changes you had to do to your code while following the recommended steps. Add snippets of code or screen captures to the report to show intermediate steps.

a$.$ Your report should not exceed $5$ pages in length.

b$.$ Note: This report can be anywhere from $2$ to $4$ pages depending on
