Java 8:将2个列表转换为Map列表

import java.util.*;
import java.util.stream.*;

public class Main {
    public static void main(String[] args) {
        List<String> keyList = Arrays.asList("key1", "key2", "key3");
        List<Integer> valueList = Arrays.asList(1, 2, 3);

        List<Map<String, Integer>> mapList = IntStream.range(0, keyList.size())
                .mapToObj(i -> Collections.singletonMap(keyList.get(i), valueList.get(i)))
                .collect(Collectors.toList());

        System.out.println(mapList);
    }
}

[{key1=1}, {key2=2}, {key3=3}]
