每次我尝试添加图像时，JavaFX中总是出现错误。java.lang.reflect.InvocationTargetException

在过去的几天里，我尽了一切努力在JavaFx上获取图像。无论我尝试什么，都是同样的错误。无论我做什么，都是同样的错误。此错误仅在图像中发生。当我使用try-catch时，打印出的异常是java.lang.IllegalArgumentException:无效URL:无效URL或未找到资源

 package application;

 import java.io.FileInputStream;
 import java.io.FileNotFoundException;

      //Creating an image 
      Image image = new Image(new 
FileInputStream("Users/user/Documents/Minesweeper/1.png"));  

      //Setting the image view

      stage.setScene(scene);

}检查图像文件的路径。路径

“Users/user/Documents/mineswipper/1.png”

是一个相对路径，请确保

Users

上方的目录是您当前的工作目录

否则，您可以将图像的绝对路径作为

FileInputStream

的参数

简单的java文件结构应如下所示：

WorkingDir | ----application | | | ----Practice.java |----1.png

Image image = new Image(new FileInputStream("1.png"));
