如何获取按条目值排序的LinkedHashMap键？

import java.util.LinkedHashMap;
import java.util.Map;
import java.util.stream.Collectors;

public class SortLinkedHashMapByValue {
    public static void main(String[] args) {
        LinkedHashMap<String, Integer> map = new LinkedHashMap<>();
        map.put("A", 3);
        map.put("B", 1);
        map.put("C", 2);

        // 按值排序并获取键
        LinkedHashMap<String, Integer> sortedMap = map.entrySet().stream()
                .sorted(Map.Entry.comparingByValue())
                .collect(Collectors.toMap(
                        Map.Entry::getKey,
                        Map.Entry::getValue,
                        (oldValue, newValue) -> oldValue,
                        LinkedHashMap::new
                ));

        // 获取排序后的键
        sortedMap.keySet().forEach(System.out::println);
    }
}
