如何使用Java Regex查找字符串中的所有重复字符序列？

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

public class Main {
  public static void main(String[] args) {
    String input = "hello world, world is beautiful";
    String pattern = "(.)\\1+";

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

    ArrayList<String> matches = new ArrayList<>();
    while (matcher.find()) {
      matches.add(matcher.group());
    }

    System.out.println("重复字符序列：" + matches);
  }
}
