Help with regex

[Jordan Smith]

Hi
I need some help.
Let's say that i have the following sentence:
It's nice outside,the sun shines!let's go swimming

and I want to capitalize the first letter of a word like this:
It's Nice Outside,The Sun Shines!Let's Go Swimming

How can I do it with

string.replaceall( )?

Thanks!

You can't do that with replaceAll().

Try putting the whole sentence into a StringBuilder, iterate through it, then use the isXXX methods of the Character class to work out whether you have a letter or not.

You can't do that with replaceAll().

You can't do that with replaceAll(), but you can do it with regex. If you would like to try... take a look at the find(), appendReplacement(), and appendTail() methods of the Matcher class.
