Please explain the use of Java's InputStream and OutputStream classes. I'm confused.

The goal of InputStream and OutputStream is to abstract different ways to input and output: whether the stream is a file, a web page, or the screen shouldn't matter. All that matters is that you receive information from the stream (or send information into that stream.)
InputStream和OutputStream的目标是抽象输入和输出的不同方式:流是文件,网页还是屏幕无关紧要。重要的是您从流中接收信息(或将信息发送到该流中)。
InputStream is used for many things that you read from.
InputStream用于您读取的许多内容。
OutputStream is used for many things that you write to.
OutputStream用于您编写的许多内容。

You can't get better explanation than this.
你无法得到比这更好的解释。
Summary:
InputStream: The abstract class; superclass of all classes representing an input stream of bytes.
InputStream:抽象类;表示输入字节流的所有类的超类。
OutputStream: This abstract class is the superclass of all classes representing an output stream of bytes. An output stream accepts output bytes and sends them to some sink.
OutputStream:此抽象类是表示输出字节流的所有类的超类。输出流接受输出字节并将它们发送到某个接收器。

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.
I / O流表示输入源或输出目标。流可以表示许多不同类型的源和目标,包括磁盘文件,设备,其他程序和内存阵列。
