Java IO principle
IO streams are used to process data transfer between devices
Input: Read external data (disk, etc storage device) to program ()


(In memory)
Output: Output program (memory) data to a storage device such as disk
Classification of streams
byte Stream (8bit), character Stream (16bit) according to operating data unit
Depending on the flow direction of the data stream: input stream, output stream
According to the role of the stream is divided into: node flow, processing flow
Abstract base class byte stream character streams
Input stream inputstreamReader
Output stream outputstreamWriter
The subclass names derived from these four classes are after the name of their parent class as the subclass name.
