Transferred from: https://www.cnblogs.com/biehongli/p/6074713.htmlThe 1:java language defines many classes that are specifically responsible for input or output in various ways, and these classes are placed in the java.io package. whichAll input stream classes are abstract class InputStream (byte input stream), or abstract class reader (character input

Basic java knowledge-network programming and IO streamIO stream Byte stream: The Stream object that processes byte data. The smallest data unit in the computer is byte. InputStream OutputStream Character stream: The character encoding problem. Encapsulating the byte

The bottom of the Java character Stream is also implemented using a byte stream, so the byte stream is converted to a character stream at a time. The conversion stream is mainly used tooutputstreamwriter: Convert byte output

In the Java language IO programming, reading a file is two steps: 1, the data in the file is converted to a stream, 2, the data inside the stream is read. The first step is completed by the system, only need to create the corresponding stream object, the object is created after the completion of Step 1, the second step

Stream classJava's streaming input/output is based on four abstract classes: InputStream, OutputStream, Reader, Writer. They are used to create specific stream subclasses. Although the program performs input/output operations through specific subclasses, the top-level class defines the basic general functionality of all stream classes.InputStream and OutputStream

Overview: Various stream types (classes and abstract classes) are located in the Java.io package, each of which inherits one of four abstract streams: Type BYTE stream Character Stream Input stream InputStream Reader Output

In recent days carefully learned Java IO stream, originally intended to watch video through the video to learn, but later found that the video does not understand and feel not very easy to use, so through the Baidu and API documents to learn Java IO streamThe IO stream can have two classifications, one is a byte

Problem:(1) The IO stream of Java uses the adornment mode, when closing the outermost stream, it automatically calls the close () side of the wrapped stream?(2) If the flow is closed sequentially, is it from the inner laminar to the outer stream closed or from the outer to t
