不清楚，帮你顶。

InputStream和OutputStream读写以单字节为基础的字节数据流；
DataInputStream和DataOutputStream 可以完成对所有基本Java类型的读写；


InputStream类 ：是一个抽象类.用于建立输入流，字节输入流的类的父类. read方法用来从输入流中读取数据
DataInputStream类：实现了DataInput接口，可用来读取格式化数据，允许应用程序从输入流中读取Java原始数据类型


good luck

A data input stream lets an application read primitive Java data types from an underlying input stream in a machine-independent way. An application uses a data output stream to write data that can later be read by a data input stream.

This abstract class(InputStream) is the superclass of all classes representing an input stream of bytes. Applications that need to define a subclass of InputStream must always provide a method that returns the next byte of input
