Chapter 2 Java stream and file operations
12.1 basic concepts of data stream
The data source is provided, and the data sink is used to receive the data. Both are called data sources.
Data sources are diverse. For more effective data input and output operations, Java abstracts data transmission between different data sources and programs into "streams ", to achieve relatively unified and simple input and ou
1. What is a streamThe stream in Java is an abstraction of a sequence of bytes, and we can imagine a water pipe, except that it is no longer the water that flows in the pipe, but the sequence of bytes. Like currents, streams in Java also have a "flow direction," where an object that is typically read into a sequence of bytes is called an input stream, and an object to which a sequence of bytes can be writte
2017-11-05 18:34:39IO streams in Java are categorized into two types, one is byte stream and the other is character stream. The character stream appears to simplify the read and write operations of text data. If the file you are manipulating is a text file, using a character stream can greatly simplify the operation, b
There are three popular product elements: waterfall stream, dynamic stream, and medal. What I call this product is vulgar and it is easy to be abused due to its popularity. PM may choose them because they are "fashionable" and "standard" and "used by others", which is terrible. I have been tossing about the dynamic stream and the medal, but I have suffered a litt
. Net stream-use stream for file replication,. net flow
Similar to various file streams and network streams in Java,. net also has various types of streams. The main purpose of a stream is to interact with files or data sources outside the application. The base class is Stream, which is defined in the namespace System
The point to be emphasized here is:The input stream and the output stream, the difference is the out and in, is relative to the program. The input stream gets the data, and the output stream is the output data. Input is the program to get external data, the output is the program to the external transmission of data, th
Detailed description of the cin standard input stream and the cin input stream
A standard input stream is used to input data to a program from an input device (such as a keyboard. in the header file iostream. the cin, cout, and cerr objects are defined in h. cin is the input stream, and others are the output
Stream is one of the most overlooked function series in PHP development (SPL series, stream series, pack function, encapsulation protocol), but it is a useful and important function. Stream can be translated as "stream", in Java, flow is a very important concept.

I. input and output streams
Input stream: when the program is running, you may need to read the required data from external storage media or other programs and use the input stream.
Output stream: After a
Php input stream: Analysis of input usage, input stream input. Php input stream: Analysis of input usage, input stream input is used to take a camera photo and then upload the function, php uses php: input to obtain the content. So I learned about php: input. Php input stream
Works [file stream and dictionary stream exercises] For s60 fp2
It's not easy. It took two weeks to complete the process. I encountered a lot of problems and solved them a little bit. However, I understood the file stream and dictionary stream. What I have not solved is:
The storage
The byte array input stream creates a byte array buffer in memory, and the data read from the input stream is saved in the byte array buffer. There are several ways to create a byte array input stream Object.The receive byte array is created as a parameter:New Bytearrayinputstream (byte [] a);Another way to create this is to receive a byte array, and two shaping
Java java.io.*; provides the relevant classes for streaming input and output of data, Io flow is an abstraction of input and output, and Java abstracts data from these different sources and targets into data streams. The benefit of unifying the input and output data as a stream is that the program does not have to be concerned with whether to read the file or the data in the network, but to treat it uniformly as an IO stream.IO
