获取List <T>的字节大小

import java.util.List;

public class ListSizeCalculator {
    public static void main(String[] args) {
        List<Integer> list = List.of(1, 2, 3, 4, 5);
        int size = getListSize(list);
        System.out.println("List size: " + size + " bytes");
    }

    public static int getListSize(List<Integer> list) {
        int elementSize = Integer.SIZE / 8; // 假设元素类型为Integer
        int listSize = list.size() * elementSize;
        int spacingSize = (list.size() - 1) * Integer.SIZE / 8; // 假设列表元素之间有间隔
        return listSize + spacingSize;
    }
}
