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
