The folders are:
我正在尝试从文件加载图像而不使用FileChooser. 这些文件夹是：
TestProject
-src
--application
---(all_the_classes_i'm_using.java)
-assets
--drawIcon.png
I want to load the image in the assets folder. I've tried:
我想在资产文件夹中加载图像。我试过了：
Image image = new Image("../assets/drawIcon.png")
Image image = new Image(getClass().getResourceAsStream("../assets/drawIcon.png"))
I've tried it with the string path "/TestProject/assets/drawIcon.png", but nothing. I don't understand how to load this image!
我已经用字符串路径“/TestProject/assets/drawIcon.png”试过了，但没有。我不明白如何加载此图像！

Set the assetsdirectory as a resource directory and then load the image as a resource from the location "/drawIcon.png":
将assets目录设置为资源目录，然后从位置“/drawIcon.png”加载图像作为资源：
URL url = getClass().getResource("/drawIcon.png");
Image image = ImageIO.read(url);
In case you want to create a javafx Image:
如果你想创建一个 javafx 图像：
Image image = new Image("/drawIcon.png");
In this case, also, mark that folder as resource folder.
在这种情况下，还要将该文件夹标记为资源文件夹。

You can use getResource(path).toString(); the path must start with /, and it starts with the verry first package in your src folder.
您可以使用 getResource(path).toString(); 路径必须以 / 开头，并且以 src 文件夹中的第一个包开头。
Image img= new Image(getClass().getResource("/path/in/your/package/structure/icon.png").toString());
Image img= new Image(getClass().getResource("/path/in/your/package/structure/icon.png").toString());
