为什么这个“新的ImageIcon（getClass（）。getResource（”files / icon.png“））。getImage（）;”让我的程序看不见？

I wrote this

我写了这个

 Image icon = new ImageIcon(getClass().getResource("files/icon.png")).getImage();

in a JFrame-extending class to then set the icon of the frame with

在JFrame扩展类中,然后设置框架的图标

this.setIconImage(icon);

I do it this way, intead of by simply using the Path, because otherwise the Icon would disappear, if I exported my Project as an executable .jar. (as seen here: Once exported, java cannot find/draw images)

我这样做,只需使用Path,因为否则Icon会消失,如果我将Project导出为可执行文件.jar。 (如下所示:一旦导出,java无法查找/绘制图像)

The problem that occurs now is, that the executable .jar works the way it should (It creates a folder, as well as a .xml-file and writes into it), but without generating a visible frame. If I run the program in eclipse however, everything works fine and I see the frame. I found out, that the problem has to be in the creation of an ImageIcon, because if I run

现在出现的问题是,可执行文件.jar以它应该的方式工作(它创建一个文件夹,以及.xml文件并写入其中),但不生成可见帧。如果我在日食中运行该程序,一切正常,我看到框架。我发现问题必须在于创建一个ImageIcon,因为如果我运行的话

getClass().getResource("files/icon.png");

everything works fine. The file is at it's place, too, so this shouldn't be the mistake.

一切正常。文件也在它的位置,所以这不应该是错误。

Hope you can help me and thanks in advance.

Okay guys, it was all my fault... @JBNizet you had the right clue again... it was the case of the path "files/icon.png" -> "Files/icon.png"

好吧,伙计们,这完全是我的错... @JBNizet你再次得到了正确的线索......就是路径“files / icon.png” - >“Files / icon.png”的情况
