Question

I’m in doubt on how to do an regex, to break an string in all white-spaces, hyphen and semicolon, it’s in Java. I’m doing:String[] tmp = input.nextLine().split("\\s:-");

but it’s not working, which is the right way ?

Answer 1

You’re currently splitting on all three of them in a row. Try character classes, which picks out any one from the selection:

String[] tmp = input.nextLine().split("[\\s:\\-]");

(hyphens have meaning in character classes, so you should escape them, too.)
