字节流继承于InputStream OutputStream,字符流继承于InputStreamReader OutputStreamWriter
后缀是Stream的都是字节流,其他的都是字符流
可以理解为字符流=字节流+编码集
字节流:
InputStream
|-- FileInputStream (基本文件流)
|-- BufferedInputStream
|-- DataInputStream
|-- ObjectInputStream
字符流
Reader
|-- InputStreamReader (byte->char 桥梁)
|-- BufferedReader (常用)
Writer
