import java.util.regex.Pattern; /** * Created by Frank * 在Java中使用正则表达式：测试模式 */ public class RESimple { public static void main(String[] args) { String pattern = "^Q[^u]//d+//."; String[] input = {"QA777. is the next flight.

输出：
'^Q[^u]/d+/.' matches 'QA777. is the next flight. It is on time.' '^Q[^u]/d+/.' doesn't match 'Quack, Quack, Quack!'
