Splitting String at "."

[Mike Himstead]

Hi,

I'd like to seperate a String containing dots (".") with the split method, this method uses regular expressions. The dot is reserved as a place holder for any character, so someString.split(".") won't work. How do I enter the dot as a regular expression?

Escape it:

String[] strings = string.split("\\.");

Duh! Thank you. I misunderstood the instructions in the Java doc.

Unfortunately, that's not hard to do. The javadoc is really just a list of supported features; to learn how to use regexes, you need to look elsewhere. There's a good tutorial here:

http://www.regular-expressions.info/

and then there's The Book:
