The end(int group) method of MatchResult Interface is used to get the offset after the end index of the match result already done, from the specified group.
Syntax:
public int end(int group)
Parameters: This method takes a parameter group from which the offset after the end index of the matched pattern is required.
Return Value: This method returns the offset after the end index matched from the specified group.
Exception: This method throws:
- IllegalStateException if no match has yet been attempted, or if the previous match operation failed.
- IndexOutOfBoundsException if there is no capturing group in the pattern with the given group.
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( 1 )); } } } |
