The Creates a successful string object whose length is fixed and cannot be modified and edited. Although you can use "+" to add new characters or strings, "+" produces a new instance of string that creates new strings objects in memory. If you repeatedly modify the string, you will greatly increase the overhead of the system.

Java regularization makes it easy to extract eligible content from strings. 1. Extract all cell phone numbers in the string: private void Getphonenum (String smsbody) {pattern Pattern = Pattern.compile ("(13|14|15|18) \\d{9}"); Matcher Matcher = Pattern.matcher (smsbody); while (Matcher.find ()) { System.out.println (Matcher.group ()); } }2. In Android development, it is sometimes necessary to extra
