Are all you Java developers so uptight?

You should do your homework, mate. Should not ask question like that ...

Read documentation on Pattern and pattern grouping should help.

I realize that. My point is it doesn't work..

See example that I included, and you will see it should have worked but
did
not, hence the error.

Just make sure that you define yourInt outside the if statement.
To be more precise:

int yourInt;
if(m.find()){
   int yourInt =
Integer.parseInt(yourString.substring(m.start(),m.end()));
}else{
   // take your action in case no integer found in yourString
}
