The end() method of MatchResult Interface is used to get the offset after the last character matched of the match result already done.
Syntax:
public int end()
Parameters: This method do not takes any parameter.
Return Value: This method returns the offset after the last character matched
Exception: This method throws IllegalStateException if no match has yet been attempted, or if the previous match operation failed.
Below examples illustrate the MatchResult.end() method:
Example 1:
// Java code to illustrate end() method  import java.util.regex.*;  public class GFG {    public static void main(String[] args)    {          // Get the regex to be checked        String regex = "(G*s)";          // Create a pattern from regex        Pattern pattern            = Pattern.compile(regex);          // Get the String to be matched        String stringToBeMatched            = "GeeksForGeeks";          // Create a matcher for the input String        MatchResult matcher            = pattern                  .matcher(stringToBeMatched);          while (((Matcher)matcher).find()) {            // Get the last index of match result            System.out.println(matcher.end());        }    }} |
Output:
5 13
Example 2:
// Java code to illustrate end() method  import java.util.regex.*;  public class GFG {    public static void main(String[] args)    {          // Get the regex to be checked        String regex = "(G*G)";          // Create a pattern from regex        Pattern pattern            = Pattern.compile(regex);          // Get the String to be matched        String stringToBeMatched            = "GFG FGF GFG";          // Create a matcher for the input String        MatchResult matcher            = pattern                  .matcher(stringToBeMatched);          while (((Matcher)matcher).find()) {            // Get the last index of match result            System.out.println(matcher.end());        }    }} |
Output:
1 3 6 9 11
