尝试在netbeans中读取文件时找不到文件异常

Question

I am making an simple application to play sounds in Java. I am able to do that when I keep the audio files in D: disk. Here is the code

in = new FileInputStream("D:\\"+selectedSounds[position]+".wav");
//Some code for playing audio

Then I placed the audio files in same package where the Jframe class is present. But when I run it prompts fileNotFound exception. Can some one tell me why this is happening.

in = new FileInputStream(selectedSounds[position]+".wav");
// I have also tried 
    new FileInputStream("./"+selectedSounds[position]+".wav");

Here is the file path

Answer 1

Your wave file, contained within the "Source Packages" won't be accessible once the program is packaged as a Jar, as the files will be embedded within the Jar itself and no longer accessible as files.

Instead, you should be using Class#getResourceAsStream , for example...

try (InputStream in = getClass().getResourceAsStream("/PlayAudio/" + selectedSounds[position]+".wav")) {
    // You now have an InputStream to your resource, have fun
} catch (IOException | NullPointerException exp) {
    exp.printStackTrace();
}
