Question

我的JavaFX代码中有这段代码

Image arrowRight = new Image("/Users/murad/Desktop/arrowright.png");
ImageView arrowRightv = new ImageView(arrowRight);

我的目标是找到桌面上的图片，然后将其放在屏幕上。但是此代码会返回此错误：

我尝试用FileInputStream做我上面所做的事情，但那不起作用。我也从Mac获得了网址，所以这绝对不错。我做错了什么？

Answer 1

参数是一个网址

"file:/Users/murad/Desktop/arrowright.png"

错误显示您在Windows上使用“c：/ ....” - 因此出现没有协议c的错误。（ “文件：/// C：/ ...”）。

找不到Javafx图像
