How to change the output?

Question

Java

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

public class Task2 {
    public static void main(String[] args) {
        String text = "ZAAABBCCDDDD";
        Matcher m = Pattern.compile("(.)\\1+").matcher(text);
        while (m.find()) {
            String sub = m.group();
            System.out.println(sub + sub.length ());
        }
    }
}

For example, there is a string "AAABCCDDDD", I need it to come out "A3BC2D4", I also get all the letters, please tell me how to fix it?

Answer 1

System.out.print(sub.substring(0, 1) + sub.length());
