Hard one for me anyway!

Question

Hi all, I would like to create a byte type which is 256bytes in size compressed.
How can I fill up a byte type with compressed data? I can use a compress file and read it
into the byte either. I need to create random data and compress it.
byte test[];
test new byte[256000];
Any ideas?
ive found this on the net but i cant make much sense of it.
Is whats below on the right track what I need?
byte[] input = "some some bytes to compress".getBytes();
// Create the compressor with highest level of compression
Deflater compressor = new Deflater();
compressor.setLevel(Deflater.BEST_COMPRESSION);
// Give the compressor the data to compress
compressor.setInput(input);
compressor.finish();
// Create an expandable byte array to hold the compressed data.
// You cannot use an array that's the same size as the orginal because
// there is no guarantee that the compressed data will be smaller than
// the uncompressed data.
ByteArrayOutputStream bos = new ByteArrayOutputStream(input.length);
// Compress the data
byte[] buf = new byte[1024];
while (!compressor.finished()) {
int count = compressor.deflate(buf);
bos.write(buf, 0, count);
try {
bos.close();
} catch (IOException e) {
// Get the compressed data
byte[] compressedData = bos.toByteArray();

from your description of your problem, I'd think you would make the buffer/byte object and then fill it with data output from an object that compresses your test file.
If this is a school assignment, it sounds like the teacher just wants you to see the benefits of compressing your data.
