我试着用Java拆分一个列表，但我对索引的混乱感到很困惑

import java.util.ArrayList;
import java.util.List;

public class ListSplitExample {
    public static void main(String[] args) {
        List<String> originalList = new ArrayList<>();
        originalList.add("A");
        originalList.add("B");
        originalList.add("C");
        originalList.add("D");
        originalList.add("E");

        int startIndex = 1;
        int endIndex = 4;

        List<String> subList = originalList.subList(startIndex, endIndex);

        System.out.println("Original List: " + originalList);
        System.out.println("Sub List: " + subList);
    }
}

Original List: [A, B, C, D, E]
Sub List: [B, C, D]
