使用java流在我的map函数中发送索引

import java.util.HashMap;
import java.util.Map;
import java.util.stream.IntStream;

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

        IntStream.range(0, map.size())
                .mapToObj(index -> {
                    String key = (String) map.keySet().toArray()[index];
                    Integer value = map.get(key);
                    return "Index: " + index + ", Key: " + key + ", Value: " + value;
                })
                .forEach(System.out::println);
    }
}

Index: 0, Key: A, Value: 1
Index: 1, Key: B, Value: 2
Index: 2, Key: C, Value: 3
