public myTest{
public static StringBuilder hhhh(String value) {
StringBuilder sb = new StringBuilder();
String strIndex = "";
// String regex = "\\d*"; 可以用String 但最终结果只有后面的数字 例子中的只能显示222222222,因为会被替代
Pattern pattern = Pattern.compile(regex);
Matcher match = pattern.matcher(value);
while (match.find()) {
if (!"".equals(match.group()))
sb.append(match.group());
}
return sb;
}
public static void main(String[] args) {
String str = "xxxxgggggg2222222[1111uuuuuuuuuu222222222";
System.out.println(hhhh(str));
}
}
执行结果:
