本文整理了Java中com.google.common.base.Ascii类的一些代码示例，展示了Ascii类的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Ascii类的具体详情如下：
包路径：com.google.common.base.Ascii
类名称：Ascii

Ascii介绍

[英]Static methods pertaining to ASCII characters (those in the range of values 0x00 through 0x7F), and to strings containing such characters.

ASCII utilities also exist in other classes of this package:

  • Charsets#US_ASCII specifies the Charset of ASCII characters.
  • CharMatcher#ASCII matches ASCII characters and provides text processing methods which operate only on the ASCII characters of a string.
    [中]与ASCII字符（值范围为0x00到0x7F）和包含此类字符的字符串相关的静态方法。
    ASCII实用程序也存在于该软件包的其他类中：
    *字符集#US#ASCII指定ASCII字符的字符集。
    *CharMatcher#ASCII匹配ASCII字符，并提供仅对字符串的ASCII字符进行操作的文本处理方法。
