In the java.net package
Java streams are divided into byte streams and hidden streams.
The top-level abstract classes of byte streams are InputStream and OutputStream.
The top-level abstract classes of the livestream include Reader and Writer.
The Bytes stream class processes Unicode characters, which are double bytes.
Standard input stream

In the previous section, we introduced how to process files in byte streams. we mentioned that for text files, byte streams do not have the encoding concept and cannot be processed by row, which is inconvenient to use, it is more suitable to use the streaming. This section describes the streaming.
First, we will briefly introduce the basic concepts of text files, the differences with binary files, encoding, and the differences between two

Lambda Expressions (lambda expression)A lambda expression is an anonymous function that is widely used in functional programming. Even Java Virtual machine-based programming languages Scala and Clojure have lambda expressions from the beginning, but until now Java does not support lambda expressions,
. Close ()It is to close the input stream and release all system resources related to the stream.
Outputstream indicates the output byte stream. The output stream accepts the output bytes and sends them to a receiver. You need to defineOutputstreamSubclass ApplicationProgramYou must always provide at least one method that can write to one output byte. It has a write byte method that writes (byte [] B) to B. length bytes are written to the output stream from the specified byte array; flush () i
