You should check whether your getClass().getResource() call actually returns a non-null value. I assume your css-file is not in the right place.

How to clear the console?
(14 answers)
Closed 2 years ago.
I want to know that how can I clear console screen in java.
The IDE I am using is IntelliJ IDEA.
For example: In C language we use to write: clrscr();
That is not possible in IntelliJ as the console is not a real terminal.
There are however different console plugins where this is possible. One of which is the Grep Console.

Using Java's File.delete() method
(4 answers)
Closed 6 years ago.
I was trying to delete some duplicate files in my folder which is around 230GB. Therefore, I searched for files with the names _2 or _3 and use the
file.delete();
However, it deletes the files that I wasn't expecting it. Can I undo that process or are those files deleted permanantly?
The Files are gone. See this Question below

So, about the workaround, If this was on windows, using recovery tools like "File Scavenger" might help you out.
