Writes len bytes from the specified byte array starting at offset off to this ByteArrayOutputStream .

Usage

From source file:com.qatickets.common.ZIPHelper.java

public static byte[] compress(byte[] data) {

    // Create the compressor with highest level of compression
    final Deflater compressor = new Deflater();
    compressor.setLevel(Deflater.BEST_COMPRESSION);

    // Give the compressor the data to compress
    compressor.setInput(data);/*from w  ww. java 2  s . c om*/
    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.
    final ByteArrayOutputStream bos = new ByteArrayOutputStream(data.length);

    // Compress the data
    byte[] buf = new byte[1024];
    while (!compressor.finished()) {
        final int count = compressor.deflate(buf);
        bos.write(buf, 0, count);
    }
    try {
        bos.close();
    } catch (IOException e) {
    }

    // Get the compressed data
    final byte[] compressedData = bos.toByteArray();

    compressor.end();

    return compressedData;
