Java Regex Replacement Issue

Question

I have the following code...

private static final String REGEX_TEAMSPLIT =
 "([0-9]*)\\s-\\s([A-Z,a-z][a-z,\\s,A-Z]*)";
...
String reg = teamNames.get(0).html();
//reg == '62401 - Breakers'
teamNumber = reg.replace(REGEX_TEAMSPLIT, "$1");
//teamNumber == '62401 - Breakers'

Now I was assuming this would leave me with only the first group per what I read online. But as you can see this is not the case. Can someone tell what I am missing?

You should use replaceAll instead of replace. (replace method does not interpret the first parameter as regular expression, but matches literally)

String REGEX_TEAMSPLIT = "([0-9]*)\\s-\\s([A-Z,a-z][a-z,\\s,A-Z]*)";
String reg = "62401 - Breakers";
String teamNumber = reg.replaceAll(REGEX_TEAMSPLIT, "$1");
System.out.println(teamNumber); // => 62401
