如何在Map中找到最小元素并返回元组(key，minimum element)？

import java.util.HashMap;
import java.util.Map;

public class MapUtils {
    public static <K, V extends Comparable<V>> Map.Entry<K, V> findMinEntry(Map<K, V> map) {
        Map.Entry<K, V> minEntry = null;
        for (Map.Entry<K, V> entry : map.entrySet()) {
            if (minEntry == null || entry.getValue().compareTo(minEntry.getValue()) < 0) {
                minEntry = entry;
            }
        }
        return minEntry;
    }

    public static void main(String[] args) {
        Map<String, Integer> map = new HashMap<>();
        map.put("A", 10);
        map.put("B", 5);
        map.put("C", 15);
        map.put("D", 3);

        Map.Entry<String, Integer> minEntry = findMinEntry(map);
        System.out.println("Key: " + minEntry.getKey() + ", Minimum Element: " + minEntry.getValue());
    }
}
