Java正则表达式替换问题

我有以下代码

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'

现在我假设这只会让我在网上看到第一组。但正如你所见，情况并非如此。有人能告诉我遗漏了什么吗？

你应该使用而不是。（

replace

方法不将第一个参数解释为正则表达式，而是逐字匹配）

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
