Stream is a newly added class of Java 8 that complements the collection class.The stream represents the data stream, and the number of data elements in the stream can be limited or infinite.The difference between
Java processing files in the class, stream at the end of the use of byte stream, reader and writer End is a character stream. The difference between the two is read and write, one is read by Byte, and the other is by character.The bottom of the character stream is the byte
Java input/output stream system and java output stream system
When I use java io streams to read and write files, it is always confusing by its various streams. There are more than 40 classes, which have been sorted out. After a while, it will be messy. I decided to sort the

Therefore, the object to be used is OutputStreamWriter. The conversion Stream object must receive a byte output stream. It can also operate the byte output
are measured in 8 bits and byte streams are measured in characters. Based on the ing characters in the code table, multiple bytes may be read at a time.
Different Processing objects: byte streams can process all types of data (such as slice and avi), while character streams can only process data of character types.
Conclusion: as long as the plain text data is processed, the use of the plain stream is pr

It's easy. Change k. stream () to k. parallelStream ()
This is simp

era, parallel programming will become more popular, but writing parallel programs is more prone to errors. During the development process, engineers can notice that the same program runs correctly in a single thread, but it may cause errors when multithreading occurs. The causes of parallel errors are usually very obscure, and they appear randomly in a test. Sin

OverviewIO streams are used to process data transfer between devicesHow Java operates on data by streamingThe objects that Java uses to manipulate the flow are in the IO packageStream-by-operation data is divided into: byte stream and character streamFlow is divided into: input stream and output
A stream is an abstract concept of a sequence of bytes.The file is the static storage form of the data, and the stream refers to the form of transmission.The flow class is divided into two categories: node stream class and Filter flow class (also called process Flow Class).The program is used to directly manipulate the target device's corresponding class called N

The IO stream of Java is divided into character stream (Reader,writer) and Byte stream (Inputstream,outputstream), and the byte stream is the name stream that reads the contents of the file into the array of bytes and then outputs
