如何在一个Java ArrayList中找到多个模式？

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

public class ArrayListPatternFinder {
    public static ArrayList<String> findPatterns(ArrayList<String> list, String pattern) {
        ArrayList<String> result = new ArrayList<>();

        for (String element : list) {
            Pattern p = Pattern.compile(pattern);
            Matcher m = p.matcher(element);

            if (m.find()) {
                result.add(element);
            }
        }

        return result;
    }

    public static void main(String[] args) {
        ArrayList<String> list = new ArrayList<>();
        list.add("apple");
        list.add("banana");
        list.add("cat");
        list.add("dog");
        list.add("elephant");

        String pattern = "a.*"; // 查找以字母"a"开头的单词

        ArrayList<String> result = findPatterns(list, pattern);

        System.out.println("匹配到的模式：");
        for (String element : result) {
            System.out.println(element);
        }
    }
}
