Java -使用自定义逻辑打印键值对的最大值

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

public class Main {
    public static void main(String[] args) {
        // 创建包含键值对的数据结构
        Map<String, Integer> keyValuePairs = new HashMap<>();
        keyValuePairs.put("A", 10);
        keyValuePairs.put("B", 20);
        keyValuePairs.put("C", 15);
        keyValuePairs.put("D", 30);

        // 调用方法打印最大值的键值对
        printMaxKeyValuePair(keyValuePairs);
    }

    public static void printMaxKeyValuePair(Map<String, Integer> keyValuePairs) {
        String maxKey = null;
        int maxValue = Integer.MIN_VALUE;

        // 遍历键值对，找到最大值的键值对
        for (Map.Entry<String, Integer> entry : keyValuePairs.entrySet()) {
            if (entry.getValue() > maxValue) {
                maxKey = entry.getKey();
                maxValue = entry.getValue();
            }
        }

        // 打印最大值的键值对
        System.out.println("最大值的键值对为：" + maxKey + " - " + maxValue);
    }
}
