Convert float[] to byte[] to float[] again

Question

So what I\'m trying to do here is get a float[], convert it to byte[], send it through the network as a datagram packet and then convert it back to

Answer 1

Sender:

ByteArrayOutputStream byteStream = new ByteArrayOutputStream();
// byteBuffer reused for every element in floatArray
ByteBuffer byteBuffer = ByteBuffer.allocate(4);
// go through the elements in the float array writing its
// byte equivalent  to the stream
for(float element : floatArray) {
  byteBuffer.clear();
  byteBuffer.putFloat(element)
  byteStream.write(byteBuffer.array());
}

// Logic for sending bytestream's bytes as datagram packet
// can get byte[] from steam by: byteStream.toByteArray();

Receiver:

ArrayList receivedValues = new ArrayList();
ByteBuffer byteBuffer = ByteBuffer.wrap(receivedBytes);

// while there is still 4 bytes left on the byte buffer
// grab the next float and add it to the received list
int position = 0;
while(byteBuffer.capactiy - position >= 4) {
  receivedValues.add(byteBuffer.getFloat(position));
  position += 4;
}

float[] result = new float[receivedValues.count];
return receivedValues.toArray(new float[receivedValues.size()]);
