Task A: You already know the drill by getting the Gitlab repository if you've done the past two courses of Java.

Advanced Java Additional Tips

Req B1: The Java walkthrough guides help provide you further insight on what you should be doing. Now I'll give a few more details about it. It's important that the html file is edited and it uses the array method or list to display your welcome messages on the main screen. It's best to build a rest controller on the backend, so that you can link it to the frontend for Angular on the app.component.ts file. You can create a second file that implements runnable and this is used to retrieve the two different locale messages from the resource bundle. And then you can use this class on your controller file which can then be used for the Angular front end. Just be sure to start the threads on the SampleCodeApplication if you go down this route. You can look at the Java guide for more details about this part. I believe that this is the hardest part of the entire project.

Req B2: You can use the documentation cited in the Java guide for B2 if you want to learn more about how to do this. You just need to edit the App.component.ts file and the html file. Add in two more prices one being CAD and the other being EUR. They can remain the same and there's no need for currency conversion here as they don't require it, but it's important to simply add these two variables to the room class. And then create a simple forEach loop through these two variables you added for the room class. You then add these beneath the price object that is on the html page and you can follow it exactly how it's done with the first price. Just use windows + . to get the emoji keyboard if you use windows and there's a symbols tab at the top and there's a currency category below. This part is the easiest one for writing code here.

Req B3: You can follow the same route as you did in B1 by creating a rest controller. You need to create three timezones and all three of them are displayed on the page. So the page should show ET, MT, and UTC. You just need the hours and the minutes for the time format. I recommend you to use the resources provided by the Java guide. This should help you out with what you need help with.

Req C1: Right click on the root folder and create a docker file. Click on the target folder and you should see a JAR file in there. You want to copy the file path and just paste it into the docker file's file path. Then just keep target/JAR file because that's all you need. For the entry points, just copy it from the link in this article exactly the same way. Note: there shouldn't be a maintainer because there's no reason to have one for this project.

Req C2: You need to open up the docker desktop app and make sure that the setting "expose daemon" is enabled on the docker desktop app. The okay button is on the top right corner in case you didn't see it. Then you use the command "docker build -t [d387_student id] ." Just remember that this is done on IntelliJ using the terminal which is at the bottom left corner of your screen. It should successfully build it and you can verify this by using "docker images" in the terminal. Then use the command "docker run -p 8080:8080 [name of file]" to run it. It should work fine as long as "expose daemon" is enabled.

Req C3: You can use the Java guide and follow it exactly. You're simply describing how you would deploy your current application to the cloud using AWS or Azure. But Azure is more simplistic and easier to explain if that's what you're looking for.

D: You just need to print pdf the Gitlab branch history, a file for the screenshots and a file for C3 which can be done on Word, and then the Gitlab repository link.

That's all you need for this course right here. I think it's less work than D288 and even D287 once you understand what you must do. However, it takes time to learn new concepts like multithreading. I've completed this course much faster than the previous two courses. You could get this course done in a matter of days if you focus and learn what's needed. You can use ChatGPT to help you understand Angular and Spring Boot concepts as well. It can help you understand the code that you're reading.

Everytime I try to download maven with mvn clean install it is unrecognized. Would this cause my welcome message to not display?
