Java Multithreading

Level 5 , Lesson 16

"Hi, Amigo!"

"Hello, Captain Squirrels, sir!"

"Do you smell that, soldier?"

"No, I don't."

"The smell is most likely coming from your terminal. Let's see what you're doing there."

"Huh? How can code stink?"

"True, it definitely can't stink... but it often has an odor."

"Captain, I'm developing a new personnel management system for the ship. Look, the project is almost ready."

"Well, it's time for you to achieve Zen in refactoring. Only then will you be able to cleanse your code. Contact Agent IntelliJ IDEA for your assignment. He'll give you all the instructions."

"Yes, sir! Carrying out your order, sir."

This task was much more fun and I think it was more useful than the final task from the previous level, the MVC task.

This is probably one of the most important large tasks so I recommend not skipping it. Even with the best planning, when working on a large project with a longer time-frame, you're likely at some point to realize that the structure of the project would be better a different way, and you'll have a big task moving methods around and stuff. If you're not careful, a disorganized approach to it will lead to forgetting certain important methods or variables that needed to be moved but weren't, and then you'll have the fun task of tracking down where the problem is. I haven't done this in Java before (since I'm new to it) but I've been through this process a lot in other languages.

Not very hard, but still a really nice task. I wish CG would provide a tabular overview for the different techniques, though.

Nice program, I really enjoyed it. I wish there were more explanations about what we are doing and what is the lesson behind every task, like they explained in the final task. It would have been nice to put the pieces of the puzzle together and not follow instructions without really knowing what technique you are using. ✌💪👍

These tasks are not super tough compared to other tasks. But definitely a lot of work!
