如何在LinkedHashMap中的特定索引/位置添加元素？

import java.util.LinkedHashMap;
import java.util.Map;

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

        int index = 1;
        String key = "D";
        int value = 4;

        LinkedHashMap<String, Integer> newMap = insertElementAtSpecificIndex(originalMap, index, key, value);
        System.out.println("Original LinkedHashMap: " + originalMap);
        System.out.println("New LinkedHashMap: " + newMap);
    }

    public static LinkedHashMap<String, Integer> insertElementAtSpecificIndex(LinkedHashMap<String, Integer> originalMap, int index, String key, int value) {
        LinkedHashMap<String, Integer> newMap = new LinkedHashMap<>();
        int currentIndex = 0;

        for (Map.Entry<String, Integer> entry : originalMap.entrySet()) {
            if (currentIndex == index) {
                newMap.put(key, value);
            }
            newMap.put(entry.getKey(), entry.getValue());
            currentIndex++;
        }

        if (currentIndex <= index) {
            newMap.put(key, value);
        }

        return newMap;
    }
}
