Solutions to garbled characters when reading java files

Solution to garbled characters when reading files in java: (Recommended: java video tutorial)

1. First, read the text file Set the encoding format to UTF-8

2. Use the InputStreamReader class to read the file. Because the character set can be specified in its construction method, specify its character set as UFT-8 format.

Example:

BufferedReader buff = new BufferedReader(new InputStreamReader(new FileInputStream("test.txt"),"UTF-8"))

Using the BufferedReader class is to use the readLine() method in this class.

The InputStreamReader class is a bridge from a byte stream to a character stream: it reads bytes and decodes them into characters using a specified character set. The character set it uses can be specified by name, explicitly specified, or the platform's default character set can be accepted.

Each call to the read() method of an InputStreamReader may result in one or more bytes being read from the underlying byte input stream. To achieve efficient conversion of bytes to characters, more bytes can be extracted from the underlying stream than required to satisfy the current read operation.
