QUESTION
When running
...ANSWER
Answered 2021-May-27 at 07:51Because an aggregate function (GROUP_CONCAT
) is present, this is an aggregate query - but because no GROUP BY
is present, it aggregates over the entire result set, leaving you with a single result row.
If you want distinct categories for each item (each group of rows corresponding to the same item), rather than distinct categories across all items, add a GROUP BY i.id
or similar.
QUESTION
I am somewhat new to coding and am trying to use the Lombok plugin to automatically create Getters/Setters e.t.c. for my fields of a specific class. In doing so I get greeted with the following error:
The error:
java: java.lang.IllegalAccessError: class lombok.javac.apt.LombokProcessor (in unnamed module @0x3b67ef9b) cannot access class com.sun.tools.javac.processing.JavacProcessingEnvironment (in module jdk.compiler) because module jdk.compiler does not export com.sun.tools.javac.processing to unnamed module @0x3b67ef9b
After doing some searching online, I found out that this error is related to an issue in OpenJDK 15 but I am currently using OpenJDK 16, hence why I am confused that I am still getting this error.
This thread claims to have a solution: https://github.com/rzwitserloot/lombok/issues/2681#issuecomment-748616687 but after implementing the plugin, it does not seem to make any difference and I still receive the error.
I have most likely made a trivial mistake since I am a beginner but if someone knows what I am missing please let me know.
Class Using @Data (Lombok): ...ANSWER
Answered 2021-Apr-07 at 07:56@FrankyFred has provided a temporary solution to be able to use Lombok: https://stackoverflow.com/a/66981165/12586904
As far as my research goes and the various responses that I received to this question, it seems like there is no possible way of running Lombok currently in OpenJDK 16. As such, an alternative to using Lombok is to put the @data
methods manually in your code. The following link briefly explains how to do this in case you are new to this topic: https://javabydeveloper.com/lombok-data-annotation/#:~:text=Lombok%20Data%20annotation%20(%20%40Data%20),as%20well%20as%20a%20constructor.

really represents:

QUESTION
My current code opens a website and logins. the next step is that I want to select a link on the next page but don't know how to get the code to click on it (first time messing with HTML code). below is a picture of the HTML behind that link. If more info is needed I can update with more pictures.
...ANSWER
Answered 2021-Feb-19 at 02:57From the description, it looks like you want to click the link with the text PRC search by selection on the page using IE VBA Automation.
If we try to check the HTML code in the image then we can notice that the page contains nested tables and what you are assuming as a link is actually a DIV
tag. So I am assuming that you want to click the DIV
.
I tried to make a test webpage with the nested tables and a similar kind of DIV and try to click the DIV using the code below.

The desired goal is when the user tries to copy the chord and lyrics and paste it in MS Word or any text editor, the post content (strings, not html) must still be the same without affecting its format which is the chord is on top of the lyrics.

QUESTION
I think I bit off a little more than I can chew. I'm creating a dummy music player and I wanted to add a button that a user can add a Song() object to the ArrayList. The problem is I add the Song objects to the Array in the onCreate() method. I have a button that inflates a PopUpView and in that view I have another button that takes the getText() from the Edit Fields and adds an item to the ArrayList, when the 'done' button is tapped the PopUPView is dismissed and the new Song() appears in the song list, but when I go back to the main menu and then go back to the song list the new Object that the user adds is no longer there.
...ANSWER
Answered 2021-Jan-20 at 20:03The problem in your code: the songs list is a property of AllSongsActivity. If you close AllSongsActivity - all data from the activity and the songs list will simply disappear!
The simple, but not correct way to save a new song use static modifier for the songs:
static ArrayList songs = new ArrayList() {{ add(new Song("Fever", "Dua Lipa", "POP", true)); add(new Song("Lonely", "Justin Bieber", "POP", false)); }};
