例子 (Example)

以下示例显示了java.util.regex.Matcher.reset（CharSequence input）方法的用法。

package cn.xnip;
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 INPUT1 = "fooabfoob";
   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());   
      }     
      matcher.reset(INPUT1);
      System.out.println("RESET");
      while(matcher.find()) {
         //Prints the offset after the last character matched.
         System.out.println("First Capturing Group, (a*b) Match String end(): "+matcher.end());   
      }     
   }
}

让我们编译并运行上面的程序，这将产生以下结果 -

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
RESET
First Capturing Group, (a*b) Match String end(): 8
