本文整理了Java中com.squareup.javapoet.ClassName.bestGuess()方法的一些代码示例，展示了ClassName.bestGuess()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。ClassName.bestGuess()方法的具体详情如下：
包路径：com.squareup.javapoet.ClassName
类名称：ClassName
方法名：bestGuess

ClassName.bestGuess介绍

[英]Returns a new ClassName instance for the given fully-qualified class name string. This method assumes that the input is ASCII and follows typical Java style (lowercase package names, UpperCamelCase class names) and may produce incorrect results or throw IllegalArgumentException otherwise. For that reason, #get(Class) and #get(Class) should be preferred as they can correctly create ClassNameinstances without such restrictions.
[中]返回给定完全限定类名字符串的新类名实例。此方法假定输入为ASCII，并遵循典型的Java样式（小写包名、大写类名），可能会产生错误的结果或抛出IllegalArgumentException。因此，#get（Class）和#get（Class）应该是首选，因为它们可以在没有此类限制的情况下正确创建ClassNameInstance。
