I. Overview of IO flow------ for manipulating dataIO streams are used to process data transfer between devices;Java operation of data is through the flow of the way;Java is used to manipulate the flow of objects are in the IO package;The flow is divided into: byte Stream (Universal) and character stream, by flow direction: input stream and output stream.Abstract

The General HD Camera product encoder can simultaneously produce two different encoding formats, collectively known as Master Stream and sub-stream, and dual-stream technology combines high-quality image transmission and narrow Bandwidth transfer. The main stream is used for local storage, and the sub-

one, processing flow:Enhanced functionality that provides performance on top of node streams.the relationship between node flow and processing flowThe node stream (byte stream, character stream) is in the front line of IO operation, and all operations must be done through them;processing streams can handle other flows (increasing efficiency or operational flexibi

Java IO learning notes (3) Conversion stream, data stream, byte array stream, and io learning notes Conversion stream1. Conversion stream: Convert byte streams to a bytes stream. After conversion, you can write content to the program with one character and one character. You

Concept:The InputStream class is an abstract class of byte input streams and is the parent class of all byte input streams.The OutputStream class is an abstract class of byte input streams and is the parent class of all byte output streams.In (can be understood as read) out (can be understood as write)One, the reading and writing of the byte streamBoth the FileInputStream class and the Fileoutstream class are used to manipulate disk files.1.FileInputStream (String name); Fill in a path name of t

The earliest use of the queue to hold data, the time node for a one-time read and FTP transmission, but the queue data is too slow, so reuse the memory stream to solve the performance of the data, on the other hand, the data for seamless FTP upload. 1, first set up a memory stream MemoryStream, and build its StreamWriter MemoryStream data_stream = new MemoryStream (); StreamWriter data_writer = new Stream

Class Number: VIP17 student Name: Xiao Wu Course name: javaseData type FlowDataOutputStream is the data type output stream, which can write the basic data type directly into the file;DataInputStream is a data type input transmission, it can be the basic data type directly read to the program, the first to write out what order, read in the order to read in accordance with the sequence of reading, sequential reading counter will be garbled or incorrect

Java The buffer stream itself has no IO function, but adds buffering to the other streams to improve efficiency, such as loading a wrapper over another stream . When the file or other target frequently read or write or operate inefficient, poor performance. This allows for more efficient reading and writing of information using buffered streams. Because the buffered str
