mahjong | HTTP based Chinese Mahjong game | Game Engine library

I'm trying to make a memory game more like mahjong. I've already completed most of it.

But the problem I'm facing is after selecting two divs/cards if they do not match they are not flipping back.

I tried to do this with an if/else statement where the selected divs are stored in a variable (in array form). But the flipping is happening to their parent div. So I used parent() to go to the parent div and add "isFlipped" class if they do not match. But it isn't working. I also tried to use map() to the variable where the selected divs are stored. It isn't working either. here's my code

I have a class called Stone, inside I have a function called return_coordinates(self), which returns the coordinates of a stone. When I print the coordinates I can see them perfectly but when I try to use them, it prints the error: TypeError: 'module' object is not callable

Here's the class:

I am making Mahjong game in swing for course project and i am trying to create a Tile, which is actually a simple JButton with some Polygons connected to it. It looks like that (https://imgur.com/af7zzTn).

I created a method, that creates the structure like above, but i have 2 problems:

1. I dont know how to "pack" structure above into "tile". Lets say, "tile" will be the object of "Tile" class that extends JButton, or JComponent, i'm not sure which one suits it better.

2. I want to add tiles like above to JLayeredPane, which will allow me, to use 3rd coordinate, like "z", or in other words, to put tiles on top of each other without bugging them, but i also dont know how to do it.

Could you please help me? I am so confused, I spent like 10 hours already fixing a problem like that, but i couldn't find the best solution on the internet. Also i would be happy, if you will make the answer as simply as possible.

Thank you in advance and here is my code:

I'm building a Mahjong game that has more buttons than Sgt. Pepper's band. The movement of the tile is simulated by showing the background of the button (tile) in question. I'd like to leverage the use of x:Name="button"and have only one click event, than 200 but the problem is in getting the name of the focused button. I can get the element with the focus but can not access the name property, if I could I would save a lot of inelegant drudgery. Here's what I'd like to do;

I am working on a mahjong project. My code contains a dynamic List> board. The abstract class Tiles gets extended by the different kind of Tiles the game has. Now im interesting on extending this small project with GUI componenets.

My thinking is to create the grid with a GridBagLayout cause my Array is dynamic sized.

A simmilar question has been asked in the past but i had hard time understanding anything from the answers and its a bit old also. old post

What i need is: when im creating an array of Jbuttons i want uponcreation of each button to place inside of them the info of each cell of the array.

Here is for example what my board array looks like: (one cell example)

I have a 'tweet' object collected using tweepy in Python. The object has attribute created_at which should give the posting time of the tweet.

Here is the case, let x be the tweet object, I have result

x.full_text

'18 suspects arrested for involvement in public gaming activities, including mahjong....'

and

x.created_at

datetime.datetime(2018, 6, 22, 10, 16, 40)

which means that the tweet was created on 22 June 2018 at 10:16 AM. But, the time in the timeline shows that it is posted at around 16-17 PM on the same date.

May I get clarification on this? thanks.

The tweet is from The Strait Times twitter account.

I am getting an exception

XmlException: Unexpected node type EntityReference. ReadElementString method can only be called on elements with simple or empty content.
