Next, let's talk about byte stream and byte stream.

Java defines two types of streams: byte streams and byte streams. Byte streams provide methods for processing the input and output of bytes. For example, when reading and writing binary data, byte streams are used. The character stream provides a convenient way to process character input and output. They use Unicode encoding, so they can be internationalized. Another point: At the bottom layer, All I/O is still byte-oriented. Character-based stream only provides a convenient and efficient way to process characters.

Byte stream

Byte streams are defined by two levels of classes. There are two abstract classes at the top level: inputstream and outputstream. Each abstract class has several sub-classes that process different devices.

Stream type	Description
Bufferedinputstream	Cached input stream
Bufferedoutputstream	Cached output stream
Bytearrayinputstream	Input stream for reading byte array content
Bytearrayoutputstream	Output stream of content written to the byte array
Datainputstream	Input stream that contains methods for reading java standard data types
Dataoutputstream	Output stream that contains methods for reading java standard data types
Fileinputstream	Input stream for reading file content
Fileoutputstream	Output stream of content written to the file
Filterinputstream	Implement inputstream
Filteroutputstream	Implement outputstream
Inputstream	Abstract class that describes Stream Input
Objectinputstream	Input stream for objects
Objectoutputstream	Used for the output stream of an object
Outputstream	Abstract class describing stream output
Pipedinputstream	Input MPs queue
Pipedoutputstream	Output Pipeline
Printstream	Output stream containing print () and println ()
Pushbackinputstream	1-Byte "unget" input stream is supported. This type of flow to the input stream returns 1 byte
Sequenceinputstream	Input stream composed of two or more input streams read sequentially
