Decompressing a Byte Array

         
import java.io.ByteArrayOutputStream;
import java.util.zip.Deflater;
import java.util.zip.Inflater;

public class Main {
  public static void main(String[] argv) throws Exception {
    byte[] input = "this is a test".getBytes();

    Deflater compressor = new Deflater();
    compressor.setLevel(Deflater.BEST_COMPRESSION);

    compressor.setInput(input);
    compressor.finish();

    ByteArrayOutputStream bos = new ByteArrayOutputStream(input.length);

    byte[] buf = new byte[1024];
    while (!compressor.finished()) {
      int count = compressor.deflate(buf);
      bos.write(buf, 0, count);
    }
    bos.close();

    byte[] compressedData = bos.toByteArray();
    Inflater decompressor = new Inflater();
    decompressor.setInput(compressedData);

    bos = new ByteArrayOutputStream(compressedData.length);

    buf = new byte[1024];
    while (!decompressor.finished()) {
      int count = decompressor.inflate(buf);
      bos.write(buf, 0, count);
    }
    bos.close();

    byte[] decompressedData = bos.toByteArray();
    System.out.println(new String(decompressedData));
  }
