ByteArrayOutputStream for shorts instead of bytes

Question

I have used the ByteArrayOutputStream which is very useful but for my needs the limits are too great (ie I am dealing with numbers in the range +-32,768)

Here is the code where I would use it:

ByteArrayOutputStream leftStream = new ByteArrayOutputStream();
ByteArrayOutputStream rightStream = new ByteArrayOutputStream();

while (din.read(temp, 0, 4) != -1) {
    if (decodedFormat.getChannels() == 2) {
       leftStream.write(temp[1] * 256 + temp[0]);
       rightStream.write(temp[3] * 256 + temp[2]);
    }
}

byte[] left = leftStream.toByteArray();
byte[] right = rightStream.toByteArray();

However the ByteArrayInputStream does not allow for values over 127 or under 128. Is there an equivalent ShortArrayOutputStream that allows shorts? Or do I have to make one myself somehow?

Answer 1

Yes, Use the DataOutputStream:

ByteArrayOuputStream bos = new ByteArrayOutputStream();
DataOutputStream dos = new DataOutputStream(bos);

dos.writeShort(val);

This works even on embedded java devices with low java version 1.3

To read in use:

ByteArrayInputStream and DataInputStream dis, and dis.readShort():

...
byte[] bytes = bos.toByteArray();
ByteArrayInputStream bis = new ByteArrayInputStream(bytes);
DataInputStream dis = new DataInputStream(bis);
short val = dis.readShort();
