Matcher end example

With this example we are going to demonstrate how to use Matcher.end() API method to get the offset after the last character matched against a pattern. In short, to use Matcher.end() API method you should:

  • Compile a String regular expression to a Pattern, using compile(String regex) API method of Pattern.
  • Use an initial String to be matched against the Pattern.
  • Use matcher(CharSequence input) API method of Pattern to create a Matcher that will match the given String input against this pattern.
  • Find the first subsequence of the input sequence that matches the pattern, using find() API method of Matcher.
  • Get the offset after the last character matched, with end() API method of Matcher.
  • Find the next subsequence of the input sequence that matches the pattern and get the offset after the last character matched.

Let’s take a look at the code snippet that follows:

package com.javacodegeeks.snippets.core;

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

public class MatcherEnd {
  public static void main(String args[]) {
    String str = "My name is Bond. James Bond.";
    String mHelper[] = { "



   ^" };
    Pattern pattern = Pattern.compile("Bond");
    Matcher m = pattern.matcher(str);

    int end = m.end();
    System.out.println(mHelper[0] + end);

    int next = m.end();
    System.out.println(mHelper[1] + next);


My name is Bond. James Bond.

My name is Bond. James Bond.


This was an example of Matcher.end() API method in Java.
