Basically, you just have to set allowExtendedOperators=true at your MongoDB datasource definition (guide). After that, you can directly use these operators.
Usage example:

QUESTION
I have a problem with the ?: operator, so I tried the if-else block and everything works fine. But when using the other operator, it just stops working.
ANSWER
Answered 2020-May-07 at 10:08?: is not an if then else
The conditional operator ?:, also known as the ternary conditional operator, evaluates a Boolean expression and returns the result of one of the two expressions, depending on whether the Boolean expression evaluates to true or false
Moreover, Console.WriteLine does not return a result, it's a void method that has side effects. So it cannot be used with an operator, full stop.
In short, just use an if then else.

I tried fixing everything, but I can't seem to find the problem. Here is my MainActivity.java file :
...ANSWER
Answered 2019-Nov-28 at 22:51I think the problem is in the line setContentView(new GamePanel(this));
Once you set the view the compiler is trying to find your textViews and button in GamePanel() class and I guess its not there.
You can resolve it by adding
setContentView(R.layout.activity_main);
before
final TextView player = (TextView) findViewById(R.id.textView);
and set dynamic UI component later.

As a quick preface, I would just like to note that this is a very beginner question, and I might be making an extremely simple mistake or just typing some code wrong. Being the self-taught coder that I am, it probably is, but please forgive me if it turns out to be true. I've looked through various coding learning websites, and I haven't found anything that has worked.
So I have some HTML and Javascript code, and I'm trying to change the HTML element's text with Javascript on a button click. Here is my code that currently works:

In answer to your question - yes! It's very useful to do so as you can drastically reduce the physical size of your code & the number of queries to the DOM!
For example, this is a valid re-use of a variable with initial document query:

I am challenging myself on a small JS application, its about a few Basketball Teams where i am calculating the average score of three games there are playing. I am stuck on a basic thing, i don't get it.
First here is the code:
...ANSWER
Answered 2019-Apr-28 at 14:04ParentNode.append does return nothing, aka undefined. As you return the result of that call from appendStringBuilder, and return that again to then finally assign it to a variable, it is no surprise that the variable is undefined at the end.
QUESTION
I am making a database that when users register, they pick 3 games they would like to play. the games are stored in a separate table (gameinfo) from the user information table (personalinformation). I am querying with the first game being shown but I would like all three shown for each user. How would I implement showing all the games?
I have tried to create different variables for each game, but that has seemed to not work as I expected and broke. the games when they are stored on the personalinformation table are stored as numbers like 1 or 2. these are linked to the gameinfo table and are the primary key for each game.

ANSWER
Answered 2019-Apr-10 at 02:05As mentioned in my comment, I would create a table to associate users and games by storing unique pairs of user_ID and game_id values. Then I'd JOIN the tables together accordingly.
However, I see that you are storing three game values for each user in the personalinformation table, in columns named firstGame,secondGame, and thirdGame.
In that case, you can JOIN the game table to each of those columns.
So, with your existing structure:
QUESTION
I am trying to create a simple program and in this program, I have managed to load sprite assets from a library class folder named 'res'. I got to a point where I wanted to add music into the program but just as it happened with images it wouldn't work unless I accessed it from a resource class folder.
On the internet, I couldn't find anything about accessing and playing audio files from this folder as I had with images. Is it possible to play music from these folders, and if so, how?
This is how I accessed my images:

Answered 2017-Apr-18 at 22:22Firstly: I suggest not to use a service at all, since it is not necessary. Just instantiate the music player in the application. But that is up to your preference.
Secondly (your actual problem): When switching activies just set a flag e.g. keepMusicOn = true; and then
