Java 将字符串与模式匹配

​

public class Main {

​

  public static void main(String[] args) {

​

    // Prepare a regular expression to represent a pattern

    /* from 

    N  o w  J a v a . c o m*/

​

    String regex = ".@.";

​

​

                // Try matching many strings against the regular expression

​

    Main.matchIt("a@k", regex);

​

    Main.matchIt("webmaster@mypkg.com", regex);

​

    Main.matchIt("r@j", regex);

​

    Main.matchIt("a%N", regex);

​

    Main.matchIt(".@.", regex);

​

  }

​

​

  public static void matchIt(String str, String regex) {

​

    // Test for pattern match

    /** from 

    n o w j a   v  a . c o m - 时  代  Java**/

​

    if (str.matches(regex)) {
