我在嘗試撥打我的ImageList時遇到了一個相當奇怪的錯誤，我不確定它爲何發生。我已經創建了一個List，並且我已經添加了項目，但我的程序仍然認爲最大索引爲零，這意味着它以某種方式爲空。誰能幫我解決這個問題嗎？謝謝！Java全局圖像列表InvocationTargetException錯誤？
列表：
setAK47Image.setImage(GunImages.gunImages.get(70));
錯誤：調用列表
public class GunImages implements Initializable {
public static List<Image> gunImages = new ArrayList<>();
public static void GunImages(){

Exception in thread "JavaFX Application Thread"
如果您的列表不包含任何元素，則請求索引爲70的對象。是由這行'CaseSpinners.AK47CaseSpinController.EmeraldPinstripeAK47（AK47CaseSpinController.java:201）'引起的。嘗試調試，應該很容易找到你的錯誤 – 2017-03-16 19:57:11
假設你正在執行引發異常的代碼行，然後再執行靜態方法。 –
你永遠不會調用'GunImages.GunImages（）;'或'GunImages gunImages = new GunImages（）;'所以你的數組永遠不會被填充。 –
