Something's wrong)

Question about the task

Resolved

Well, I feel I've done everything expected, but the validator doesn't believe I've met any of the requirements, beginning with the very declaration of the ClientGuiController class. I'm really at a loss, as I was pretty confident about this code:). What am I missing?

I have great news for you. The view component is already done. I've added a ClientGuiView class. It uses the javax.swing library. You should really study every line of this class. If everything is clear, that's wonderful. If not, be sure to find answers to your questions using the debugger, documentation, or an Internet search.

We just need to write the controller component:
1) Create a ClientGuiController class that inherits Client.
2) Create and initialize a ClientGuiModel model field, which is responsible for the model.
3) Create and initialize a ClientGuiView view field, which is responsible for the view. Think about what you need to pass to the constructor when the object is initialized.
4) Add a GuiSocketThread inner class that inherits SocketThread. The GuiSocketThread class must be public. It overrides the following methods:
a) void processIncomingMessage(String message) - It should set a new message on the model and trigger an update on the view of the message.
b) void informAboutAddingNewUser(String userName) - It should add a new user to the model and trigger an update of the view of the users.
c) void informAboutDeletingNewUser(String userName) - It should remove a user from the model and trigger an update on the view of the users.
d) void notifyConnectionStatusChanged(boolean clientConnected) - It should call a similar method on the view.
5) Override the following methods in the ClientGuiController class:
a) SocketThread getSocketThread() - It should create and return a GuiSocketThread object.
b) void run() - It should get a SocketThread object via the getSocketThread() method and call its run() method. Figure out why we don't need to call the run() method on a separate thread, like we did for the console-based client.
c) getServerAddress(), getServerPort(), getUserName(). They should call the identically-named methods on the view.
6) Implement the ClientGuiModel getModel() method, which should return the model.
7) Implement the main() method, which should create a new ClientGuiController object and call its run() method.

Start a GUI-based client and several console-based clients, and make sure that everything works correctly.

Requirements:

The client package should correctly declare the ClientGuiController class and a nested GuiSocketThread class.
The ClientGuiController class must correctly declare and initialize the fields listed in the task conditions.
The processIncomingMessage() method must be implemented in the GuiSocketThread class in accordance with the task conditions.
The informAboutAddingNewUser() method must be implemented in the GuiSocketThread class in accordance with the task conditions.
The informAboutDeletingNewUser() method must be implemented in the GuiSocketThread class in accordance with the task conditions.
The notifyConnectionStatusChanged() method must be implemented in the GuiSocketThread class in accordance with the task conditions.
The ClientGuiController class's getSocketThread() method should return a new GuiSocketThread object.
The ClientGuiController class's run() method should get a SocketThread object via the getSocketThread() method and call its run() method.
The ClientGuiController class's getServerAddress(), getServerPort(), and getUserName() methods should call the appropriate methods on the view object.
The ClientGuiController class's getModel() method should return the model field.
The ClientGuiController class's main() method should create a new ClientGuiController object and call its run() method.
The ClientGuiController class must be a descendant of the Client class.

SimpleDateFormat simpleDateFormat = new SimpleDateFormat(pattern); // To get the current date, you must use the Calendar class and getTime() method. Calendar calendar = Calendar.getInstance(); Date currentDate = calendar.getTime(); String formattedDate = simpleDateFormat.format(currentDate); // The response must include the name of the client // who sent the request and is waiting for a response, // e.g. if Bob sent the "time" request, we should send the following response: // "Information for Bob: 12:30:47". sendTextMessage("Information for " + name + ": " + formattedDate); } } }

Line 45 of the ClientGuiController class. It should be: public static void main(String[] args) What is happening when the program is started is that Java is not finding that main() method inside the ClientGuiController because the signature (the name and parameters) is not the correct signature for a main() method. There is a main() method that resides in the parent, the Client class, and that is what is being called instead. You are not allowed to use the @Override on static methods, which would have been nice to be able to in this case as that tag would have created an error on the incorrect main() method since it didn't over ride the same method in the parent class.

Thank you very much, Guadalupe! I really didn't notice I hadn't passed the String[] args. My code is finally working, hurray))

It took me a lot of time yesterday to figure out the problem with this code. I went over the code in the ClientGuiController at least ten times without notcing the missing String[] args from the main() method; and was breaking apart your code in all the other classes looking for any mistakes that could be the issue. Do you use intelliJ? If so did you know about the "live templates" that you can use? Basically you can type a few characters and hit tab and get a snippet of code. I shared a picture below with 4 screen shots. In the first one by just typing the character p intellisense brings up a bunch of suggestions. Every suggestion with a "stamp" icon is one the these snippets of code. I can use the arrow, highlight one, hit tab and code would be inserted in at the cursor. In the second frame you can see I highlighted "psvm". The third frame is a continuation of that that shows the result of me hitting the tab button with "psvm" highlighted: a main method is inserted where the cursor was. The fourth frame shows that simply typing 'm' brings up a snippet of code for the main method, which is actually my preferred way of doing that; hitting 'm' then tab. You should try different keys to see what code snippets are already included in IntelliJ. I know there are ones for getting the last element of an array, 'for loops', sys.out.println.

Thank you very much for your help and advice! Yes, I should use these templates definitely more actively)
