Files.newReader介绍

[英]Returns a buffered reader that reads from a file using the given character set.

java.nio.file.Path equivalent: java.nio.file.Files#newBufferedReader(java.nio.file.Path,Charset).
[中]返回使用给定字符集从文件读取的缓冲读取器。
JAVA尼奥。文件路径等价物：java。尼奥。文件Files#newbuffereder（java.nio.file.Path，Charset）。
