Java get matches group of Regex

Question

Given following Java expression codes:

boolean match = row.matches(\"(\'.*\')?,(\'.*\')?\");

if the match is true, it

Answer 1

To access the groups you need to use Matcher: Pattern.compile(regex).matcher(row).

Then you can call find() or matches() on the matcher to execute the matcher and if they return true you can access the groups via group(1) and group(2).

String row = "'what','ever'";
Matcher matcher = Pattern.compile("('.*')?,('.*')?").matcher( row );
if( matcher.matches() )
{
  String group1 = matcher.group( 1 );
  String group2 = matcher.group( 2 );
}
