导出的jar文件不播放声音

Question

I made this method to play audio in my class and it works fine. but for some reason when i export it to a jar file nothing happens. I tried other solutions but i just get null-pointer exceptions. does anyone have an idea what i'm doing wrong

public void welcome(){
        try { 
            AudioInputStream audioInputStream = AudioSystem.getAudioInputStream(new File("sound/garage1.wav").getAbsoluteFile());
            Clip clip = AudioSystem.getClip();
            clip.open(audioInputStream);
            clip.start();
        } catch(Exception ex) {
            System.out.println("Error with playing sound.");
            ex.printStackTrace();
        }
 }

Answer 1

if you load the file like this (not as ressource of a class), the folder "sound" containing the "garage1.wav" has to be located in the working directory when you execute the jar, because new File("") points to the working directory. For example: if you execute the jar with a double click on it, the folder "sound" must have the same parent folder as the jar.
