This class is a subclass of InflaterInputStream that reads and uncompresses data compressed in gzip format. To create a GZIPInputStream, you must simply specify the InputStream it is to read compressed data from, and optionally specify a buffer size for the internal decompression buffer. Once a GZIPInputStream is created, you can use the read() and close() methods as you would with any input stream.
public class GZIPInputStream extends InflaterInputStream {
