英文:
I don't know why my java application cannot find an image
问题
我在 src 文件夹中有我的图像，但当运行代码的这部分时，它不起作用。
Image img = Toolkit.getDefaultToolkit().getImage("background.png");
我认为问题与图像不在正确的目录有关，但我不知道应该把它放在哪里。我正在使用 IntelliJ，它没有向项目中添加图像的方法。
英文:
I have my image in the src folder, but when this part of the code is run it does not work.
Image img = Toolkit.getDefaultToolkit().getImage("background.png");
I think that the problem has to do with the image not being in the right directory, but I don't know where to put it. I am using IntelliJ and it does not have a way to add images to your project.

你可以直接在你的src文件夹中创建一个类，或者在你的包(package)中创建一个类，然后添加这段代码：
URL urlImage = YourClassName.class.getResource("yourimage.png");
Image image = ImageIO.read(urlImage);
如果你的目录结构是这样的：src/image 和 src/package/class
你可以使用 ../ 来返回上一级文件夹。例如，使用上面的目录结构，你的代码将如下所示：
URL urlImage = YourClassName.class.getResource("../yourimage.png");
Image image = ImageIO.read(urlImage);
更详细的解释是，在文件结构中，../ 表示返回上一级文件夹。希望这有所帮助！
英文:
You can make a class directly in your src folder, or in your package, and then add this code:
URL urlImage = YourClassName.class.getResource("yourimage.png");
Image image = ImageIO.read(urlImage);
If you have this structure: src/image and src/package/class
you can use ../ to go to the above folder. For example, using the structure above, your code will look like this:
URL urlImage = YourClassName.class.getResource("../yourimage.png");
Image image = ImageIO.read(urlImage);
For more explanation, in file structure ../ goes one folder above. I hope I helped!
