import java.util.regex.Matcher;

import java.util.regex.Pattern;/**来自 时代Java公众号 - nowjava.com**/


public class Main {

  public static void main(String[] args) {

    Pattern pattern = Pattern.compile("[^cf]at");

    Matcher matcher = pattern.matcher("bat");

    if (matcher.matches())

      System.out.println("Match.");

    else

      System.out.println("Does not match.");

  }
