String regex = “([a-zA-Z]+[0-9]+)";
Pattern pattern = Pattern.compile(regex);
String strInput = “age45 salary3456 50000 title";
Matcher matcher = pattern.matcher(strInput);
StringBuffer sb = new StringBuffer();
while (matcher.find()) {
String replacement = matcher.group(1).toUpperCase();
matcher.appendReplacement(sb, replacement);
}
matcher.appendTail(sb);
System.out.println(“置換後文字列:\r\n" + sb.toString());
}
}
