For example
The Matcher m=Pattern.com running (" (\ \ d +) "). The Matcher (" a12b3cc5de67a ");
While (m. ind ()) {
System. The out. Printf (" % s ", m.g roug (1));
}

M=Pattern.com running (" (\ \ w) "). The matcher (" go wuhan go China ");
While (m. ind ()) {
String s=Character. ToUpperCase (m.g roup (1). The charAt (0)) + m.g roup (1) the substring (1);
System. The out. Printf (" % s ", s);
}
