The end() method of Matcher Class 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 Matcher.end() method:
Example 1:
import java.util.regex.*;
public class GFG {
public static void main(String[] args)
{
String regex = "(G*s)" ;
Pattern pattern
= Pattern.compile(regex);
String stringToBeMatched
= "GeeksForGeeks" ;
Matcher matcher
= pattern
.matcher(stringToBeMatched);
MatchResult result
= matcher.toMatchResult();
System.out.println( "Current Matcher: "
+ result);
while (matcher.find()) {
System.out.println(matcher.end());
}
}
}

Output:
Current Matcher: java.util.regex.Matcher[pattern=(G*s) region=0,13 lastmatch=]
