Below examples illustrate the Matcher.group() method: Example 1: Java // 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 Matcher matcher = pattern .matcher(stringToBeMatched); // Get the current matcher state MatchResult result = matcher.toMatchResult(); System.out.println("Current Matcher: " + result); while (matcher.find()) { // Get the group matched using group() method System.out.println(matcher.group()); } } } Output: Current Matcher: java.util.regex.Matcher[pattern=(G*s) region=0, 13 lastmatch=] s s Example 2: Java // 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 Matcher matcher = pattern .matcher(stringToBeMatched); // Get the current matcher state MatchResult result = matcher.toMatchResult(); System.out.println("Current Matcher: " + result); while (matcher.find()) { // Get the group matched using group() method System.out.println(matcher.group()); } } } Output: Current Matcher: java.util.regex.Matcher[pattern=(G*G) region=0, 11 lastmatch=] G G G G G Reference: Oracle Doc Comment More infoAdvertise with us Next Article Matcher group() method in Java with Examples K Kirti_Mangal Follow Improve Article Tags : Java Java - util package Java-Functions Java-Matcher Practice Tags : Java Similar Reads Matcher group(int) method in Java with Examples The group(int group) method of Matcher Class is used to get the group index of the match result already done, from the specified group.
