Java 全局映像列表调用目标异常错误

Question

我在尝试调用Image List时遇到一个相当奇怪的错误，我不确定为什么会发生。我创建了一个List并向其中添加了项目，但我的程序仍然认为最大索引为零，这意味着它以某种方式为空。谁能帮我解决这个问题？谢谢！

列表：

public class GunImages implements Initializable {
    public static List<Image> gunImages =  new ArrayList<>();
    public static void GunImages(){
            /*

这个答案相当简单，我从来没有叫过GunImages.GunImages((;所以这个列表从来没有被填满。
