I need to regex a string.
<NAME> [NUM1:]<NUM2>
I want to get mandatory NAME and NUM2. I do not need the optional NUM1. If NUM1 is present is is separated by a : to NUM2.
E.g.
tim 20 => NAME: tim, NUM2: 20
tommy 123 => NAME: tommy, NUM2: 123
eve 9:234 => NAME: eve, NUM2: 234
Thats my pattern and matching. It is working well.
Pattern pat = Pattern.compile ("^(.+)\\ ([0-9]\\:)?(.+?)$");
Matcher mat = patp.matcher (myline);
if (matpack.matches () == true)
{
System.out.println ("NAME: " + mat.group (1) + ", NUM2: " + mat.group (3));
}
As you can see I have ( ) around the optional NUM1 to say the number AND the : are optional (?). Therefore I need to use group 1 (NAME) and group 3 (NUM2) to get the matching values.
How can I change my regex-term to group the number and the : of NUM1 together for the ? but not have it as a group?
I want to have group 1 for NAME and group 2 for NUM2.
