Constructors

Sr.No.Constructor & Description
1InflaterInputStream(InputStream in)Creates a new input stream with a default decompressor and buffer size.
2InflaterInputStream(InputStream in, Inflater inf)Creates a new input stream with the specified decompressor and a default buffer size.

4boolean markSupported()Tests if this input stream supports the mark and reset methods.
5int read()Reads a byte of uncompressed data.
6int read(byte[] b, int off, int len)Reads uncompressed data into an array of bytes.
7void reset()Repositions this stream to the position at the time the mark method was last called on this input stream.
8long skip(long n)Skips specified number of bytes of uncompressed data.
