Regex expression gets 1) instead of just the number

nop :

I want to make a pattern matching for the following:

FirstName LastName (ID: 1)

Code:

Pattern pattern = Pattern.compile("^([A-Za-z0-9_ ].*)(ID: (?<customerId>[0-9].*))$");
Matcher matcher = pattern.matcher(customer.getSelectedItem().toString());
if (matcher.matches()) {
    String customerId = matcher.group("customerId"); // returns 1) instead of just 1
    ...

The problem is that my regex expression returns 1) instead of just 1 or any number.

Toto :

Remove the .* tahtt means 0 or more any character (including the closing parenthesis):

Pattern.compile("^([A-Za-z0-9_( ]*)(ID: (?<customerId>[0-9]*))\\)$");

You can also remove the groups if you don't want to capture:

Pattern.compile("^[\\w ]*\\(ID: (?<customerId>[0-9]*)\\)$");
