推荐答案

我不确定你的问题在哪里，但我最好的猜测是：

i'm not sure where your problem is, but my very best guess would be:

你的图片位置不是适当！ （忽略其他类，它只是一个测试项目^^）

your image location is not suitable! (ignore the other classes, it's just a test project ^^)

我复制/粘贴你的代码，我使用了我的自定义图像，它可以正常使用我！

i've copy/pasted your code, i used my custom image and it works fine with me!

在你的eclipse项目中创建一个文件夹，但不要在你的SOURCE目录（!!!）然后参考这样的图像：

make an folder in your eclipse project BUT NOT IN YOUR SOURCE dir (!!!) and then refer to the image like this:

Image img1 = Toolkit.getDefaultToolkit().getImage("img/index.png");
