Many may have a better understanding of the CAP project, including her working principles and applicable scenarios. Therefore, the blogger has prepared a live broadcast to explain it to you, this video is a live video.
I didn't plan to launch this livestream, so I was not prepared for it. So some explanations were not in place or unexpected during the

. Inputstream, outputstream
Abstract class for processing byte streams
Inputstream is the superclass of all classes of the byte input stream. We generally use its subclass, such as fileinputstream.
Outputstream is the superclass of all classes of the byte output stream. We generally use its subclass, such as fileoutputstrea
video signal recording and rapid release for live video playback.

The procedure (Operation role: editing) is described as follows:
If (with Operation permission ){
If (there is a broadcast ticket on the day ){

Outputstreamwriter is a bridge between outputstream and writer. Its subclass filewriter is actually a specific class that implements this function (you can study sourcecode ). Functions and usage are very similar to those of outputstream, and their corresponding graphs will be shown later.

Reader itself is an input class of the livestream. The definition of this class is as follows:

This class is also an abstract class. If you want to use this class, you must use its subclass. If you want to write content to the file, you should use the filereader subclass. The constructo

8. bytes stream Writer/Reader
In Java, the character adopts the Unicode standard. A character is a 16-bit character, that is, a character is expressed in two bytes. To this end, JAVA introduces Stream processing characters.
1. Reader abstract class
The abstract class used to read the livestream. The sub-classes must implement only read (char [], int, int) and close () methods (). However, most su
sources, there are far more than the three types of sources visible on the market, even cameras have many categories. For a complete live video cloud service covering streaming, transmission, and playback, supporting as many collection sources and playback terminals as possible is an unavoidable and difficult task.
To support access to all the collection sources on the market, we adopt an open design in the SDK. As long as the collection source implementation follows the corresponding interface

2. Differences between the byte stream and the byte stream
When operating byte stream operations, the buffer zone is not used, but the file itself is directly operated, while the byte stream uses the buffer zone during operati

of these four words, and I am very familiar with them.
When to use byte stream? When should I use the livestream?
First, you need to know that any data stored on the hard disk is stored in binary format. Byte streams allow you to read arbitrary files. A byte stream reads one byte at a time. When a byte stream reads one or more bytes, it searches for the specified encoding table and returns the corresponding encoding. Therefore, the byte stream can on

First, let's talk about the time when the input stream is used for obfuscation and the time when the output stream is used. Program --> program, using InputStream. The output is also relative to the program. The program writes the information to (.txt) and uses OutputStream from the program -->. txt.
