This class is a subclass of java.io.FilterInputStream ; it reads a specified stream of compressed input data (typically one that was written with DeflaterOutputStream or a subclass) and filters that data by uncompressing (inflating) it. To create an InflaterInputStream , specify both the input stream to read from and an Inflater object to perform the decompression . Once an InflaterInputStream is created, the read( ) and skip( ) methods are the same as those of other input streams. The InflaterInputStream uncompresses raw data. Applications often prefer one of its subclasses, GZIPInputStream or ZipInputStream , that work with compressed data written in the standard gzip and PKZip file formats.
