switch | Write apache and nginx conf | Runtime Evironment library

First time actually using anything to do with swing - sorry for the poor code and crude visuals!
Using swing for a massively over-complicated password checker school project, and when I came to loading in a JMenuBar, it doesn't render properly the first time. Once I run through one of the options first, it reloads correctly, but the first time it comes out like this: First render attempt
But after I run one of the methods, either by clicking one of the buttons that I added to check if it was just the JFrame that was broken or using one of the broken menu options, it reloads correctly, but has a little grey bar above where the JMenuBar actually renders: Post-method render

The code for the visuals is as follows:

I am a beginner learning from a tutorial on how to change the colour of a selected area of a picture with a range of colour options.

I can figure out how to change one area, but unsure how to implement the other areas.

What I want to achieve is to click on the selected area, it highlights the border (CSS), then change the colour by using the colour options.

What is the best way to implement this? I'm I correct in thinking maybe a switch statement with onclick to select the specific area of the picture?

We just got Telerik controls today and I am trying to "switch out" the old controls for the new Kendo UI MVC Controls.

I have a select2 multi-selection dropdownlist and I am trying to send the "selected to paramters through the Kendo UI dataSource to the controller method to return the specific records.

Here is my .cshtml Razor code:

I know this question has been asked multiple times but I cannot seem to find an answer. I have a component named DynamicTable which renders JSON as a data table. It has been tested in multiple other pages and works correctly. Here I have put it into a React-Bootstrap tab container. The data pull works correctly but the page is not re-rendering when the fetch is complete.

Here is the code I am using

I'm using PDFDownloadLink from the react-pdf package to generate a PDF on the fly in my application and allow the user to download a report based on data being passed to the component that generates the PDF document. However, there are more than 400 pages that need to be rendered in this PDF, and this operation blocks the main thread for a few seconds. Is there any way to make this operation asynchronous, so the rest of the application will continue to function while the PDF is being generated? Also I would like to be able to cache the results, since the data being passed to the component can come from about 8 different arrays of data, which don't change very much, so switching between these arrays I would rather not to have to render the PDF all over again if the PDF for that given array has already been generated once before... I'm guessing the blob data needs to be stored somewhere, perhaps localStorage?

I'm new to React. I have two button for sort. But I want to change for sort both ascending and descending in one button.

So I am relatively new to programming, and I have been working on this task app, where I want to save the data such as task name and more, given by the user. I am trying to accomplish this using Room. Now, initially, when I tried to do it, the app would crash since I was doing everything on the main thread probably. So, after a little research, I came to AsyncTask, but that is outdated. Now finally I have come across the Executer. I created a class for it, but I am a little unsure as to how I can implement it in my app. This is what I did :
