// Filewriter Public class filewriterdemo {// Delimiter stream: Applicable to text files, which are operated in characters and often used together with buffered streams./*** Operation steps of the livestream:* 1. Create a producer stream* 2. Create a buffer stream* 3. Perform read/write operations* 4. Close the stream*

large-capacity files due to the data format conversion, slower, inefficient.The so-called low-level I/O function is input and output in bytes, and the data format is not converted at input and output. This input and output is in binary form. Typically used to transfer a batch of bytes between memory and device. This input and output speed, high efficiency, general large-capacity file transfer with unformatted conversion of I/O. However, it is not easy to use.A file

The difference between the byte stream and the character stream: direct according to the picture to draw the conclusion: conclusion: The byte stream does not use the buffer in the operation itself, it is directly operated in the file itself, and the character stream uses the buffer in the operation, through the buffer

1. Overview of Bufferedoutputstream/bufferedinputstream (byte buffer stream)It is really much faster to define an array than it was to read one byte at a time, so it seems that a buffer is still very good. Since this is the case, then, when Java began to design, it also took into account this problem, it is specifically provided with a buffer byte class. This class is called: Buffer Class (High efficiency Class)　　Write Data : Bufferedoutputstream　　Rea

1. The difference between byte and char: binary encoding is used for direct transmission when word Throttling is used, and the encoding problem of the local system is involved when Byte and Char are used, some APIs in Java I/o Perform Stream Conversion Based on the parameter configurations of the operating system or JVM. This simplifies some programming processes. However, in network communication, we strongly recommend that you use byte streams to re

Print Flow:The print stream is the most convenient class for outputting information, note that contains the byte print stream printstream and the character print stream: PrintWriter. The print flow provides a very convenient printing function,You can print any type of data information, such as: Decimal, Integer, String.Review:Before printing the information need

The Readline method is the method in the bufferedreader class of the bytes stream. The keyboard read method is the byte stream inputstream method. Can I change byte stream to the bytes stream and use the Readline method of the SWAp stream buffer? Inpustream in = system. In;

Streaming* The stream abstracts the external storage of data (usually objects ).* Streaming APIs are abstract-It provides interfaces for reading data from the storage and writing data to the storage, but does not care what the storage is-Defined in s32std. h, and the file stream defined in s32file. h· This header file is associated with Estor. Lib.* Based on two key concepts-
