This article is based on Linux environment operation, readers need to have a certain knowledge of Linux before readingThe InputStream consists of three methods as follows: int read (): reads a single byte from the input stream, returning the byte data read (byte data can be converted directly to int type) int read (byte[] b): reads up to b.length bytes of data from the input stream and stores it in byte array B, returning the actual number of bytes read int read (byte[] b, int o

Differences between fileinputstream and filereader Core tips: 1) File class introduction File class encapsulates the function of operating the file system on the user's machine. For example, you can use the File class to obtain the last modification time, move the object, or delete or rename the object. In other words, the stream class focuses on the file content, while the file class focuses on the main

InputStream objects created with the FileInputStream class can be used to read content from a file. The two commonly used constructors are as follows: FileInputStream (String FilePath) FileInputStream (File fileobj) Both constructors will throw filenotfoundexception exceptions. Where FilePath is the full pathname of the file, and Fileobj is the file object that
