MatchResult end(int group) method in Java with examples.
The java.util.regex.MatcheResult interface provides methods to retrieve the results of a match.
You can get an object of this interface using the toMatchResult() method of the Matcher class. This method returns a MatchResult object which represents the match state of the current matcher.
The end(int group) method of this interface accepts an integer representing a particular group and returns the offset after the last match occurred in the specified group.
Example
import java.util.Scanner;
import java.util.regex.MatchResult;
import java.util.regex.Matcher;
import java.util.regex.Pattern;
public class Example {
public static void main( String args[] ) {
String regex = "(.*)(\d+)(.*)";
//Reading input from user
Scanner sc = new Scanner(System.in);
System.out.println("Enter input text: ");
String input = sc.nextLine();
//Instantiating the Pattern class
Pattern pattern = Pattern.compile(regex);
//Instantiating the Matcher class
Matcher matcher = pattern.matcher(input);
//verifying whether a match occurred
if(matcher.find()) {
System.out.println("Match found");
}
MatchResult res = matcher.toMatchResult();
int end = res.end(1);
System.out.println(end);
}
}Output
