Classes involved in Java read I/O operations

First, take a look at the classes involved in I/O operations:

The first two groups mainly describe the format of data transmission, one is a byte, and the other is a character.

The latter two groups mainly describe the way data is transmitted.

1.1.1 The following is a byte-based I/O operation interface.

InputStream interface

OutputStream interface

1.1.2 Character-based I/O operation interface

Writer class

Reader class

1.1.3 Character and Byte conversion interface

The conversion process is read as follows:

Where InputStreamReader is a conversion from byte to Character Bridge, from InputStream to reader conversion needs to specify the encoding character set, otherwise it will appear garbled.

The process in which it is written is converted as follows:
