JAVA BufferedInputStream And BufferedOutputStream Infomation

Thank you Visiting In Advance BY IT PROGRAMMING WORLD

BufferedInputStream

java.​io

public class BufferedInputStream extends FilterInputStream

A BufferedInputStream adds functionality to another input stream-namely, the ability to buffer the input and to support the mark and reset methods. When the BufferedInputStream is created, an internal buffer array is created. As bytes from the stream are read or skipped, the internal buffer is refilled as necessary from the contained input stream, many bytes at a time. The mark operation remembers a point in the input stream and the reset operation causes all the bytes read since the most recent mark operation to be reread before new bytes are taken from the contained input stream.

 BufferedOutputStream

java.​io

public class BufferedOutputStream extends FilterOutputStream

The class implements a buffered output stream. By setting up such an output stream, an application can write bytes to the underlying output stream without necessarily causing a call to the underlying system for each byte written.
