Summary of examples of character stream usage in Java

This article mainly introduces relevant information that explains the difference between character stream and byte stream in Java. Friends who need it can refer to the difference between character stream and byte stream in Java 1. What is a stream? What is a stream in Java? To abstract the sequence of bytes, we can imagine that there is a water pipe, but now the water flowing in the pipe is no longer water, but a sequence of bytes. Like water flow, a stream in Java also has a "flow direction". Generally, an object from which a sequence of bytes can be read is called an input stream; an object from which a sequence of bytes can be written is called an output stream. . 2. Byte stream The most basic unit of byte stream processing in Java is a single byte, which is usually used to process binary data. The two most basic byte stream classes in Java are InputStream and OutputStream, which represent the basic input byte stream and output byte stream respectively. Both the InputStream class and the OutputStream class are abstract classes. In actual use, we usually use a series of their subclasses provided in the Java class library. Below we

Introduction: php, basics: [PHP] Back to the basics (IO stream): IO streams are used to process data transmission between devices. Java operates on data through streams. Java objects used to operate streams are all streamed in IO packages. According to the operation data, it is divided into two types: byte stream and character stream. According to the flow direction, the stream is divided into: input stream and output stream. Character stream abstract base class: Reader Writer file operation, write and obtain the FileWriter object, new out, construction parameter: String file name; at this time, a file will be created in the specified directory. If it already exists, it will be overwritten; this method will throw an IOException and call Fi

Introduction: PHP file operation Author: zccst file operation has always been my weakness. When developing in Java, those I/O streams (byte stream, character stream and mutual conversion) always make me dizzy. Fortunately, PHP's file operations are relatively simple and somewhat C-like. Now gradually used, the most commonly used are fopen, fwrite, fcolse. Others accumulate slowly. I found a good ppt today. Very basic and practical. The address is: http://wenku.baidu.com/vi
