Java Reflection detailed This article is still using a small example to illustrate, because I always feel that the case driven is the best, or only to see the theory, read also do not understand, but suggest that after reading the article, in retrospect to look at the theory, will have a better understanding. Start the text below. Case 1 Gets the complete package name and class name from an object

Using Java regularization makes it easy to extract eligible content from a string.1. Extract all the 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 extract the

Addpart ("Pic", bin). Addpart ("key", Keybody). Addpart ("Cardtype", Typebody). Build ();Httppost.setentity (reqentity);Httppost.setconfig (config);Perform network requests and

Computer questions (Elementary)-Snowball example code (Java) In the previous section, the effects of the stars are achieved. This section will implement a small example of snowball rolling. here we need to use the re-painting and thread knowledge. The Code is as follows: im

only move to the right, do not have to return to the left. of which, Dfa[i][j]Represents the position (0~J) where the next text character ' CharAt (i+1) ' should match the pattern string when representing the current character ' charAt (i) ' in a text string.Here we introduce a finite automaton DFA to initialize the value of dfa[][]. Take the pattern string "AABACB" as an example, matching the PAT's DFA state diagram as follows: The corresponding
