Example 1

import java.util.regex.Matcher;
import java.util.regex.Pattern;
public class MatcherHitEndExample1 {
	   public static void main(String[] args) {
	      Pattern p = Pattern.compile("(a*v)(java)");
	      // get a matcher object
	      Matcher m = p.matcher("aabjavaaabjavaabjavab");
	      System.out.println("find(): "+m.find());
	      System.out.println("hitEnd(): "+m.hitEnd());    
	   }
	}

Output:

find(): false
hitEnd(): true

Example 2

import java.util.regex.Matcher;
import java.util.regex.Pattern;
public class MatcherFitEndExample2 {
public static void main(String[] args) {
	      int count=0;
	 	Pattern p = Pattern.compile("java");  
	      Matcher m = p.matcher("aabjavaaabjavaabjavab");
	      System.out.println("find() : "+m.find());
	      while(m.find()) {
	    	  count=count+1;
	      }
	      System.out.println("hitEnd(): "+m.hitEnd()); 
	      System.out.println("number of match by find() method : "+count);
	   }
}

Output:

find() : true
hitEnd(): true
number of match by find() method : 2

Example 3

import java.util.regex.Matcher;
import java.util.regex.Pattern;
public class MatcherFitEndExample3 {
public static void main(String[] args) {
	      Pattern pattern = Pattern.compile("java");
	      Matcher matcher = pattern.matcher("aabjavaaabjavaabjavab");
	      while(matcher.find()) {
	         //Prints the index after the last character matched.
	         System.out.println("First Capturing Group, (a*b) Match String end(): "+matcher.end());    
	      }
	      System.out.println("hitEnd(): "+matcher.hitEnd());    
	   }
}

Output:

First Capturing Group, (a*b) Match String end(): 7
First Capturing Group, (a*b) Match String end(): 14

First Capturing Group, (a*b) Match String end(): 20
hitEnd(): true
