Where should I put my resources for a Java program?
提问by user3150201
I'm programming in Java using Eclipse.
我正在使用 Eclipse 用 Java 编程。
I have recently tried playing a sound file in my program. I did this:
我最近尝试在我的程序中播放声音文件。我这样做了：
URL url = this.getClass().getResource("ih.wav");
audioIn = AudioSystem.getAudioInputStream(url);
clip = AudioSystem.getClip();
clip.open(audioIn);
clip.start();
This only worked, when I tried to put ih.wav in the bin folder, as if the bin folder was the "base folder" for my project. Putting the file in the main folder of the project, didn't work. Putting it in the src folder, didn't work too.
这仅在我尝试将 ih.wav 放在 bin 文件夹中时才起作用，就好像 bin 文件夹是我项目的“基本文件夹”一样。将文件放在项目的主文件夹中，没有用。把它放在 src 文件夹中，也没有用。
Can someone explain to me where to put my resources for Java programs? Also, does it matter if I import the resources into Eclipse? Thanks
有人可以向我解释将我的 Java 程序资源放在哪里吗？另外，如果我将资源导入 Eclipse 有关系吗？谢谢

Tried to create a resources folder in the main project folder, still gives me a NullPointerException:
试图在主项目文件夹中创建一个资源文件夹，仍然给我一个 NullPointerException：
URL url1 = this.getClass().getResource("res/ah.wav");
audioIn = AudioSystem.getAudioInputStream(url1);
clip1 = AudioSystem.getClip();
clip1.open(audioIn);
URL url2 = this.getClass().getResource("res/eh.wav");
audioIn = AudioSystem.getAudioInputStream(url2);
clip2 = AudioSystem.getClip();
clip2.open(audioIn);
URL url3 = this.getClass().getResource("res/ih.wav");
audioIn = AudioSystem.getAudioInputStream(url3);
clip3 = AudioSystem.getClip();
clip3.open(audioIn);
clip1.start();
clip2.start();
clip3.start();

Best practice would be to create a folder (depending on your package structure) that is called either resor resourceswhere you will keep project related resources such as any images or sound files.
最佳做法是创建一个文件夹（取决于您的包结构），该文件夹被称为res或resources您将保存项目相关资源（例如任何图像或声音文件）的位置。
Depending on preference, either put this folder in your main project folder MyProject/resor put it inside the relevant package, e.g. main.java.res
根据偏好，将此文件夹放在主项目文件夹中MyProject/res或将其放在相关包中，例如main.java.res

To adhere more to your question, I'm not too familiar with the getResources()method, so instead I would personally recommend using some code similar to:
为了更多地坚持您的问题，我对该getResources()方法不太熟悉，因此我个人建议使用一些类似于以下内容的代码：
File file = new File("ih.wav");
audioIn = AudioSystem.getAudioInputStream(file);
clip = AudioSystem.getClip();
clip.open(audioIn);
clip.start();
That shouldproduce the results you are looking for, given that you change the path of he file accordingly (e.g. "main/resources/ih.wav"or wherever you are storing the file.
考虑到您相应地更改了文件的路径（例如或存储文件的任何位置），这应该会产生您正在寻找的结果"main/resources/ih.wav"。

Under your project, create a directory called resources. In here place all you "resources" you want to access from within your application. These will bundled with your application as embedded resources.
在您的项目下，创建一个名为resources. 在这里放置您想要从应用程序中访问的所有“资源”。这些将作为嵌入式资源与您的应用程序捆绑在一起。
From within your application use either
从您的应用程序中使用
this.getClass().getResource("/ah.wav")
or
或者
this.getClass().getResource("/resources/ah.wav")
Assuming that you placed the files at the top level of the resourcespath. If they're in a sub-directory, you'll need to provide the full path...
假设您将文件放在resources路径的顶层。如果它们位于子目录中，则需要提供完整路径...
