"Hi, Amigo!"

"Hello, Captain Squirrels, sir!"

"Soldier, we have a secret mission for you. You will develop a tool for creating web pages."

"Cool, web pages. But why do we need our own editor?"

"What do you mean 'why'? Soldier, orders aren't for discussion. They're for execution."

"Yes, sir! Write a tool for creating web pages."

"Don't shout, soldier. Didn't they tell you this is a top secret mission."

"Contact Agent IntelliJ IDEA to begin. He'll bring you up to speed."

"He'll also provide all further instructions."

"May I proceed, sir?"

"Proceed."

So, our HTML editor is ready, but how do we really test it?

I am sorry, but for me it was really unclear what the model actually is. Ok, it is object of class HTMLDocument referenced by document. But as Model in MVC pattern represents login of the application, the part of the “model”, are also actions (in package of the same name) and listeners logical parts of the model? Or this is just some additional logic? Also, could someone please help me with understanding of relation between objects? Is the relation between controller and view aggregation? (objects can exist independently and can be changed)

I lost the logic at the beginning. This task is very strange. P.s. Did you find a job after this course?

It's a good overview of working with Java's built-in menu system. Most of the things that seem like they will be extremely difficult at the beginning to the project (changing fonts, opening/closing files, parsing HTML code) are actually really simple because Java can do it for you. I'm hoping there's still more to come on working with the other parts of Swing, mainly drawing shapes, displaying images, and animation.

I really liked this task. It could be my inexperience or short sight, but it seemed to muddy my simple understanding of MVC models. the view & controller are clearly defined in one class, yet the model is spread out through the many actions and listeners classes. I personally would have put all of them in a package called Model. Also, the view implemented some actions, for example undo(), that would have been better implemented in the Model Package if such a thing existed, or in a class of it's on. This way the View would have only user interface/UI/GUI which calls out actions from the many classes in the Model package, and the Controller handles the file source.
