Read a file into a String with one line

This is one of those that I never remember, but use a lot whenever I want to pull an entire file into a String quickly.

String text = new Scanner(new File("file.txt")).useDelimiter("\\A").next();

\\A is the start of the file, so Scanner is going to try and split on the beginning of the file. Since there’s only one beginning, there’s only one next.
