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

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
