正则表达式在java问题,多个匹配

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

public class RegexExample {
    public static void main(String[] args) {
        String input = "abc123def";
        String regex = "\\d+";

        Pattern pattern = Pattern.compile(regex);
        Matcher matcher = pattern.matcher(input);

        if (matcher.find()) {
            System.out.println("Found a match: " + matcher.group());
        } else {
            System.out.println("No match found.");
        }
    }
}

public class RegexExample {
