publicstaticfinalInputStream in The “standard” input stream. This stream is already open and ready to supply input data. Typically this stream corresponds to keyboard input or another input source specified by the host environment or user. in是一个InputStream类型的对象,所以只需要了解InputStream即可。

Listing2-4A simple listing in Java demonstrating user keyboard input 与Python 相比,Java 确实需要更多的设置。用 Java 写的程序可以用所谓的 Java 包来扩展;这些基本上是数据容器,为你的项目添加新的特性和功能。清单 2-4 中的第一行为任何 Java 程序添加了交互功能,当我们需要用户输入时,它需要出现。
Java also has a System.in object, for reading from the keyboard, but it must be processed to be useful. In this example, ConsoleIn is assumed to be a previously defined class (that uses System.in), which contains the method Readlnt() for reading an integer value. As with the other ...

a streaming audio application must simultaneously read the digital audio off the network, decompress it, manage playback, and update its display to the user. A word processing program should always be ready to respond to keyboard and mouse events, no matter how busy it is reformatting text or...
For example, java.io.Reader has a method called read(), which reads bytes of data from a file or network connection. This is written in C because it actually calls the read() system call for Unix, Windows, Mac OS, BeOS, or whatever. The JDK source kit includes the source for all ...
{int_byte = System.in.read();if(_byte ==-1)return; System.out.print((char) _byte); } } System.in.read()reads bytes from the standard input stream, which defaults to the keyboard but can be redirected to a file. When the stream is redirected to a file, -1 is returned when the...
