abstract int
read()
Reads the next byte of data from the input stream.
int
read(byte[] b, int off, int len)
Reads up to len bytes of data from the input stream into an array of bytes.
int
read(byte[] b)
Reads some number of bytes from the input stream and stores them into the buffer array b.
synchronized void
reset()
