Java I/O - 如何解压缩一个字节数组

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

public class Main {
  public static void main(String[] argv) throws Exception {
    byte[] compressedData = null;
    Inflater decompressor = new Inflater();
    decompressor.setInput(compressedData);
    ByteArrayOutputStream bos = new ByteArrayOutputStream(compressedData.length);
    byte[] buf = new byte[1024];
    while (!decompressor.finished()) {
      int count = decompressor.inflate(buf);
      bos.write(buf, 0, count);

    }
    bos.close();
    byte[] decompressedData = bos.toByteArray();

  }
}
