Java JavaInputStreamReader. Similarly, we could pass an input stream for reading from a … InputStream in = socket.getInputStream(); BufferedReader br = new BufferedReader (new InputStreamReader (in)); // The other side says hello: String text = br. The input file can be an ordinary ASCII,one byte per character text file. You don't want to do that in this case, so just use: // Deliberately not closing System.in! BufferedReader class can be used to read data line by line by readLine() method. JavaInputStreamReader is a bridge between byte streams and character streams. Then, finally, we call the readLine method using this object. Here, the internal buffer of the BufferedReader has the default size of 8192 characters.
java的new BufferedReader(new InputStreamReader(System.in)) 流 JAVA /IO 基本小结 通过一行常见的代码讨论:new BufferedReader(new InputStreamReader(System.in)) /*** *** 看到这篇文章挺好的,就转了.版式我改了一下,方便阅读. BufferedReader bufferedReader = new BufferedReader (new InputStreamReader (System. To read console input, we shall wrap the System.in (standard input stream) in an InputStreamReader which again wrapped in a BufferedReader class.. BufferedReader reads text from the console, buffering characters so as to provide for the efficient reading of user input. It is recommended to wrap an InputStreamReader within a BufferedReader for optimal efficiency.. BufferedReader reader= new BufferedReader(new InputStreamReader(System.in))解读 lzh_86 2017-09-26 22:09:41 6502 收藏 6 分类专栏: java
The InputStreamReader is then passed to a BufferedReader for better efficiency. BufferedReader br = new BufferedReader(new InputStreamReader(System.in)); You would have noticed that we have initialized the BufferedReader object br by calling one of its constructors that takes Reader object as a method argument. It reads bytes and decodes them into characters using a specified charset. В общем-то, если перевести его название на русский, все выглядит очевидно — “считыватель входящих потоков”. in )); 构造一个BufferedReader,里面存放在控制台输入的字节转换后成的字符。 BufferedReader 사용법 BufferedReader bf = new BufferedReader(new InputStreamReader(System.in)); //선언 String s = bf.readLine(); //String int i = Integer.parseInt(bf.readLine()); //Int 선언은 위에 있는 예제와 같이 하시면 됩니다. It is used to create a buffered character input stream that uses the default size for an input buffer. Example of reading data from keyboard by InputStreamReader and BufferdReader class. A Readerstream automaticallytranslates the characters fromthe disk file formatinto the internal charformat. To use the BufferedReader class, we need to wrap the predefined object System.in in the InputStreamReader class, then pass this wrapped object to the BufferedReader constructor. BufferedReader in = new BufferedReader(new FileReader( fileName ) ); FileReaderis used for input ofcharacter data from a disk file. in)); Мы передаем поток System.in объекту InputStreamReader. The characters in the input file might be fromother alphabets supported by the UTF …
