Output correct grammar

[JordashTalon]

I have a string like this:

"this is a cool string . and another cool segment of the same string . "

As you can see the periods have an extra space I need to change that too:

"this is a cool string. and another cool segment of the same string."

I tried

String=String.replaceAll(" . ", ". ");

But that doesn't work it also replaces all the a's in the string, not sure why, I think it has something to do with the Hex values or something like that or I need to use Regular Expressions.

Any help would be appreciated.

Thanks

why not reply to your other post first before starting a new one? Have a period in string, how to make it look nicer

oh sorry didn't notice the updates on the other thread, my bad. your other post worked, you are a regular expression genius!
