How to convert little endian to big endian in java .wav files

Question

I've got the following problem:

I need to convert audio bytes (byte[]) from

48kHz, 16 bit, stereo, PCM signed, BIG ENDIAN

to

48kHz, 16 bit, stereo, PCM signed, LITTLE ENDIAN

in java and save it as .wav file.

                      List<byte[]> orderedBytes = bytesFromVoice;

                            /*
                            Here i need to sort the bytes
                             */

                            int size = 0;
                            for (byte[] bs : orderedBytes) {
                                size += bs.length;
                            }
                            byte[] decodedData = new byte[size];
                            int i = 0;
                            for (byte[] bs : orderedBytes) {
                                for (int j = 0; j < bs.length; j++) {
                                    decodedData[i++] = bs[j];
                                }
                            }

                            //writing to file
                            try {
                                getWavFile(getNextFile(), decodedData);
                            } catch (IOException exception) {
                                exception.printStackTrace();
                            }

Found a way ... it's pretty easy:

private void getWavFile(File outFile, byte[] decodedData) throws IOException {
    AudioFormat format = new AudioFormat(48000.0F, 16, 2, true, true);
    boolean convertable = AudioSystem.isConversionSupported(
                           new AudioFormat(48000, 16, 2, true, false), format);
    System.out.println("Can be converted: " + convertable);
    AudioSystem.write(new AudioInputStream(
        new ByteArrayInputStream(decodedData), format, decodedData.length), 
        AudioFileFormat.Type.WAVE, outFile);
    File converted = new File("converted.wav");
    try {
        AudioInputStream audioInputStream = AudioSystem.getAudioInputStream(
            new AudioFormat(48000, 16, 2, true, false), 
            AudioSystem.getAudioInputStream(outFile));
        AudioSystem.write(audioInputStream, AudioFileFormat.Type.WAVE, converted);
    } catch (UnsupportedAudioFileException e) {
            e.printStackTrace();
    }
}
