Instructions To prepare you for this assignment, read the module 3 content and follow the embedded learning activities. Read the following scenario: As a continuation of the previous assignment, review the following scenario. Code&Code is a small company dedicated to Software Development. Their engineering team to which you belong, is working on writing a Web Application as an MVP for a new customer. The code name for this App is “Loggy”, which is meant to offer functionality for a personal journal where users can log their daily activities through text, voice and video. You have moved forward a few weeks ahead and have finished the core functionality. The challenge you have in front of you now, is to perform additional actions to attachments such as, automatic translation, transcoding, automatic closed captioning. These actions are triggered once the media file is uploaded. As an initial step, you must create the skeleton of the back-end service for performing the automatic closed captioning under these assumptions: The closed captioning is performed through an external service (AWS or GCloud). There should be an internal controller that: Receives the recordings to be processed from a requester Sends the recordings to the external service Receives its response Updates the recoding with the resulting closed captioning; and Responds back to the requester The recordings can be processed simultaneously, but there is a limit of only 5 concurrent processes that can be handled by the sender. Therefore, there should be a queue that will act as a buffer for the overhead. Once the recording is processed, the external service responds with a callback, therefore a listener should be ready to receive that request and update the object with a text file containing the strings for the closed captioning. Only audio and video can be processed. The processing time depends of the length of the recording. Task Main class Write a Main class that you will use as the simulator for testing you Classes Closed-captioning controller Write the class that will simulate the recording to be processed, which contains an id, the media, a length and the strings for closed captioning. Write a class that will be the actual controller (or spooler). Write a class that will act as the worker for processing closed captioning though an external service Implement the queue and callback actions Submission Your submission should include: Java code of your final solution. Report of your observations on the changes you had to do to your code while following the recommended steps. Add snippets of code to the report to show intermediate steps. Remember that although the scenario and resulting model may be used for future activities, the main goal is to practice what you have learned in this module, so do not be worried about finding the perfect solution for this case. And keep in mind that System.out.println() will be enough for the purposes of illustrating your model.
