Thread: Representing the return key in a regular expression

Quick question that my last program made me want to ask. I found another solution that didn't require me to do this for the program, but it got me curious: How do you represent a return key in a regular expression?

Let's say you want to hold execution pending a return key press (which is what I was doing). One way to do that would be to rig a scanner on System.in using a delimiter pattern that says to accept only return characters. So for instance:

Pattern p = Pattern.compile("//Regular expression goes here.");

What character would one use in that regular expression for representing the return key?

Thanks as always,

Excellent question for a search engine.
At the risk of sounding rude, we have better things to do with our time than your research.

Which it does, indeed. I resent the implication that I'm too stupid to look for the answer elsewhere before asking here. I am asking because I could not find it.

You say you have better things to do - so instead of wasting time "doing my research," you waste your time insulting me. Bravo.
