Problem Description:

How to reset the pattern of a regular expression?

Solution:

Following example demonstrates how to reset the pattern of a regular expression by using Pattern.compile() of Pattern class and m.find() method of Matcher class.

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

public class Resetting {
   public static void main(String[] args) 
   throws Exception {
      Matcher m = Pattern.compile("[frb][aiu][gx]").
      matcher("fix the rug with bags");
      while (m.find())
         System.out.println(m.group());
      m.reset("fix the rig with rags");
      while (m.find())
         System.out.println(m.group());
   }
}
