Matcher.start(): Find the starting point

 

import java.util.regex.Matcher;
import java.util.regex.Pattern;

public class Main {
  public static void main(String args[]) {
    String candidateString = "This is a test. This is another test";
    Pattern p = Pattern.compile("test");
    Matcher matcher = p.matcher(candidateString);

    // Find the starting point of the first 'test'
    matcher.find();
    int startIndex = matcher.start();
    System.out.println(candidateString);
    System.out.println(startIndex);

    // Find the starting point of the second 'test'
    matcher.find();
    int nextIndex = matcher.start();
