[jira] Closed: (LANG-573) Add new APIs to StringUtils
(countLowerCase, countUpperCase, countDigits)
[ https://issues.apache.org/jira/browse/LANG-573?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Henri Yandell closed LANG-573.
------------------------------
Resolution: Won't Fix
I think a better solution is to use regexps here:
public static int countMatches(String text, String regex) {
Pattern p = Pattern.compile(regex);
Matcher m = p.matcher(text);
int count = 0;
while(m.find()) {
count++;
}
return count;
}
Closing as WONTFIX, though I've added the code above to LANG-397 as a possible add for a RegexUtils.
