在你们给我另一个链接之前,我已经研究了我的案子两天,没有运气:(
我的问题是如何在不获取错误消息的情况下声明ImageView / AudioClip / MediaPlayer
首先,让我向您显示错误消息:

我知道此问题是由于图像声明引起的:
现在的代码行如何(给我错误):
URL background = this.getClass().getResource("resources/Image/MenuBackGround.jpg");
ImageView menuBack = new ImageView(new Image(background.toString()));
mainPane.getChildren().add(menuBack);
以前如何(类似于此并且可以正常工作):
try(InputStream pathIntro = Files.newInputStream(Paths.get("resources/Image/ControlBack.png"))){
intro = new ImageView(new Image(pathIntro));
controlPane.getChildren().add(intro);
}
在使audioClip或MediaPlayer正常工作时,我也遇到同样的问题。
我只是想知道为什么这会导致我出现问题,以及实现这种目标的正确方法是什么?
The resources folder is not in src and is directly under the project folder
