Capitalize first letter of words in a string

Question

I'm having trouble figuring out how to transform a string into camel case in groovy. Say I start out with a string that looks like "1-800 FOO.BAR". Ultimately, I want this to turn into "1800FooDotBar". I've been able to get 1800FOODotBar by doing the following:

String str = "1-800 FOO.BAR"
String tempStr = str.replaceAll(/(?i)\.com/, "DotCom")
String newStr = tempStr.replaceAll(/\\W/, "")

I'm just not sure how to get rid of those capital letters in the middle. I've come across some information about a capitalize() method that should be able to help, but I'm just not familiar enough with Groovy to know how to use it. I think I need to split the string into individual strings for each word and then capitalize the first letter of each of those strings, but then how do I build the end result back up? I know that similar questions have been asked, but I'm just not seeing how to take that information and make complete Groovy code from it. Thanks in advance!

Very roughly:

String str = "1-800 FOO.BAR"
println str.replaceAll(/\./, " Dot ").split(/[^\w]/).collect { it.toLowerCase().capitalize() }.join("")
=> 1800FooDotBar
