Data input and output (I/O for input/output)The input and output of standard input devices and standard output devices are referred to as standard I/OThe input and output of files stored on an external disk are referred to as files I/O.The input and output of the specified string bucket in the memory are referred to as string I/O.

java.io uses design patterns such as adapter pattern decoration mode to solve the socket and input-output problems of character streams.
A byte stream can only be processed at a time, in order to more easily manipulate the data, it adds a socket flow.
Problem Introduction:
Why is the buffer stream more efficient than ordinary file-byte throttling?
An operation without buffering, which writes a byte ever

Elementary stream
In the MPEG-2, bit streams that contain encoded images, sounds, or data are called the basic stream ES (elementary stream ), it only contains one type of data (audio, video, or subtitle). What we call "audio", "video", or "bit stream" is elementary stream,
Java input/output streamPre-knowledge preparation1. Basic Java SyntaxBasic principle:While the program is running, it may be necessary to read the required data from an external storage medium or other program, which requires the use of an input stream object. The input stream points to the source called it, and the program reads the source data from the input stream
java.io uses design patterns such as adapter mode decoration mode to solve the problem of socket and input and output of character streams.The byte stream can only process one bytes at a time, and in order to manipulate data more conveniently, it joins the socket stream.Problem Introduction: Why is buffered stream more efficient than normal file-byte throttling?Without buffering, a byte is written for each
