BufferedInputStream class « BufferedInputStream « Stream for Input « File Stream

A BufferedInputStream adds the ability to buffer the input and to support the mark and reset methods.

Constructor	Summary
BufferedInputStream(InputStream in)	Creates a BufferedInputStream and saves its argument, the input stream in, for later use.
BufferedInputStream(InputStream in, int size)	Creates a BufferedInputStream with the specified buffer size, and saves its argument, the input stream in, for later use.

Return	Method	Summary
int	available()	Returns an estimate of the number of bytes that can be read (or skipped over) from this input stream without blocking by the next invocation of a method for this input stream.
void	close()	Closes this input stream and releases any system resources associated with the stream.
void	mark(int readlimit)	See the general contract of the mark method of InputStream.
boolean	markSupported()	Tests if this input stream supports the mark and reset methods.
int	read()	See the general contract of the read method of InputStream.
int	read(byte[] b, int off, int len)	Reads bytes from this byte-input stream into the specified byte array, starting at the given offset.
void	reset()	See the general contract of the reset method of InputStream.
long	skip(long n)	See the general contract of the skip method of InputStream.
