本文整理了Java中java.text.Bidi类的一些代码示例，展示了Bidi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。Bidi类的具体详情如下：
包路径：java.text.Bidi
类名称：Bidi

Bidi介绍

[英]Implements the Unicode Bidirectional Algorithm.

Use a Bidi object to get the information on the position reordering of a bidirectional text, such as Arabic or Hebrew. The natural display ordering of horizontal text in these languages is from right to left, while they order numbers from left to right.

If the text contains multiple runs, the information of each run can be obtained from the run index. The level of any particular run indicates the direction of the text as well as the nesting level. Left-to-right runs have even levels while right-to-left runs have odd levels.
[中]实现Unicode Bidirectional Algorithm。
使用Bidi对象获取双向文本（如阿拉伯语或希伯来语）的位置重新排序信息。这些语言中水平文本的自然显示顺序是从右到左，而数字顺序是从左到右。
如果文本包含多个运行，则可以从运行索引中获取每个运行的信息。任何特定梯段的级别指示文本的方向以及嵌套级别。从左到右的跑步级别为偶数，而从右到左的跑步级别为奇数。
