推荐答案

这是个大话题！我建议您首先阅读 I/O 流:

This is a big topic! I would recommend that you begin by reading I/O Streams:

一个 I/O 流代表一个输入源或输出目标.一个流可以代表许多不同的各种来源和目的地，包括磁盘文件、设备、其他程序和内存数组.

An I/O Stream represents an input source or an output destination. A stream can represent many different kinds of sources and destinations, including disk files, devices, other programs, and memory arrays.

流支持多种不同的类型数据，包括简单的字节，原始数据类型，本地化字符和对象.一些流简单地传递数据；别人操纵并以有用的方式转换数据.

Streams support many different kinds of data, including simple bytes, primitive data types, localized characters, and objects. Some streams simply pass on data; others manipulate and transform the data in useful ways.
