Java - 将LinkedHashMap键/值放入各自列表的简单方法？

import java.util.ArrayList;
import java.util.LinkedHashMap;
import java.util.List;
import java.util.Map;

public class LinkedHashMapToList {
    public static void main(String[] args) {
        LinkedHashMap<String, Integer> linkedHashMap = new LinkedHashMap<>();
        linkedHashMap.put("key1", 1);
        linkedHashMap.put("key2", 2);
        linkedHashMap.put("key3", 3);

        List<String> keys = new ArrayList<>();
        List<Integer> values = new ArrayList<>();

        for (Map.Entry<String, Integer> entry : linkedHashMap.entrySet()) {
            keys.add(entry.getKey());
            values.add(entry.getValue());
        }

        System.out.println("Keys: " + keys);
        System.out.println("Values: " + values);
    }
}
