示例

以下示例顯示了java.time.Matcher.hitEnd()方法的用法

package com.zaixian;

import java.util.regex.Matcher;
import java.util.regex.Pattern;

public class MatcherDemo {
   private static String REGEX = "(a*b)(foo)";
   private static String INPUT = "aabfooaabfooabfoob";
   private static String REPLACE = "-";

   public static void main(String[] args) {
      Pattern pattern = Pattern.compile(REGEX);

      // get a matcher object
      Matcher matcher = pattern.matcher(INPUT);

      while(matcher.find()) {
         //Prints the offset after the last character matched.
         System.out.println("First Capturing Group, (a*b) Match String end(): "+matcher.end());
      }
      System.out.println("hitEnd(): "+matcher.hitEnd());
   }
}

編譯並運行上面的程式，這將產生以下結果 -

First Capturing Group, (a*b) Match String end(): 6
First Capturing Group, (a*b) Match String end(): 12
First Capturing Group, (a*b) Match String end(): 17
hitEnd(): true
