Sr.No.	Method & Description
1	int available() Returns 0 after EOF has been reached, otherwise always return 1.
2	void close() Closes this input stream and its underlying input stream, discarding any pending uncompressed data.
3	int read() Reads a single byte of compressed data from the input stream.
4	int read(byte[] b, int off, int len) Reads compressed data into a byte array.
5	long skip(long n) Skips over and discards data from the input stream.
