Description

The Possesive Quantifier [X{n,}+] matches the X present at least n times.

Example

The following example shows the usage of Possesive quantifier.

package com.tutorialspoint;

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

public class ReluctantQuantifierDemo {
   private static final String REGEX = "T{2,}+";
   private static final String INPUT = "abcdTatTTfgfgTTTW";

   public static void main(String[] args) {
      // create a pattern
      Pattern  pattern = Pattern.compile(REGEX);
      
      // get a matcher object
      Matcher matcher = pattern.matcher(INPUT); 

      while(matcher.find()) {
         //Prints the start index of the match.
         System.out.println("Match String start(): "+matcher.start());
      }
   }
}

Let us compile and run the above program, this will produce the following result −

Match String start(): 7
Match String start(): 13
