Access files (.wav) in Java package

I want to access my .wav files which are in a package inside my project.

For example I have two packages:

  • program
  • sounds

From inside the program/something.class I'd like to play the sounds/asound.wav. How is this possible?

clip.open(AudioSystem.getAudioInputStream(new File(filename)));
clip.start();
//.... something inbetween
clip.stop();

Here filename is C:\\projects\\something\\sounds\\, but how is it possible to just give a relative path to the asound.wav in the package?

Solution

  • Use ClassLoader.getResourceAsStream to load resources via the same infrastructure you are using for class loading. Depending on the class loader, this can be a file in a directory, the content of a local JAR file or a remote resource.

    getClass().getClassLoader().getResourceAsStream("asound.wav");

    As indicated by the name of the method, you will get an InputStream for the resource, and not a File. If you consider that the resource may be part of another file, such as a JAR file, this makes sense, as File objects always point to single files, and not parts of them.
