How to completely load audio but play it later?

So, I have an AudioInputStream, which reads from a FileInputStream. I want to close the FileInputStream which will close the AudioInputStream.

Is there any way to load the audio completely, so that I don't have to stream it directly from the file?

You can store it in a Java Clip.

Example:

Clip clip = AudioSystem.getClip();
clip.open(/*your AudioInputStream*/);

Make clip a field, to use it later.

If you want an AudioInputStream, you can load the entire file in to a byte array:

static AudioInputStream load(File file) throws IOException {
    try (FileInputStream in = new FileInputStream(file)) {
        ByteArrayOutputStream bytes = new ByteArrayOutputStream();

        byte[] buf = new byte[4096];
        for (int b; (b = in.read(buf)) > -1;) {
            bytes.write(buf, 0, b);
        }

        return AudioSystem.getAudioInputStream(
            new ByteArrayInputStream(bytes.toByteArray());
    }
}

Or in Java 7:

static AudioInputStream load(File file) throws IOException {
    return AudioSystem.getAudioInputStream(
        new ByteArrayInputStream(Files.readAllBytes(file.toPath()));
}
