"JoinChatRoomOutpurBoundary" should be changed to "JoinChatRoomOutputBoundary.

When we changed the versions of and , we found that the entire project seemed to be compatible with the computer. But when running the program, I found that there seemed to be a problem with the layout of the real-time updated messages. I wonder if it was because the versions of and were changed. I hope to further explore and solve this unexpected situation.

The return null CommonUserFactory.
Remove pom.xml temporarily.
Specify the preparefailedview into prepareNameFailView, prepareInvalidPWFailView, prepareRepeatPWlView, also add message poped out for signup cannot success.

Revised the User module, fixed the compile and stylish problems and created 2 files: CommonUser and CommonUserFactory, meanwhile change User and UserFactory into interface.
Fixed some stylish problems in ChatRoom module.

The messages cannot updated in the same computer in the different user chatroom.

When we send message on the different computer (internet), the message cannot synchronize on time and may disappear. We need try to fix it.

• Revised the User module, fixed the compile and stylish problems

There are some code in both Weather and Joke API call are unused, try to delete them. Also some name need to be changed to match the whole file naming style

The message cannot store on the local. Try to use the same way as user storage to solve this problem.

Now we have successfully do the coding work for our program to get the Weather Report by Weather Api call. Now it works when enter proper existing city. But there is still some issue left to fix about the error message and what should a fail view look like when enter a non-existing city or something else. The error is in the DataAccessObject about Weather Api

So far, our latest version of the project has successfully implemented the creation of chat rooms, sending and receiving messages, and viewing weather reports. However, the project also has certain problems. When the entire file is run on different computers or laptops, sometimes the program cannot be run as scheduled because the versions of and in pom.xml are not compatible with all computers. . Consideration should be given to adjusting the version appropriately to make the program compatible.
