我在尝试拨打Image List时遇到一个相当奇怪的错误，我不确定它为什么会发生。我创建了一个List并且我已添加了项目，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(){

调用列表的行：
setAK47Image.setImage(GunImages.gunImages.get(70));

答案 0 :(得分：0)
这个答案相当简单，我从未调用GunImages.GunImages（）;这个名单从未填满。
