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

Float介绍

[英]The Float class wraps a value of primitive type float in an object. An object of type Float contains a single field whose type is float.

In addition, this class provides several methods for converting a float to a String and a String to a float, as well as other constants and methods useful when dealing with a float.
[中]Float类将基本类型Float的值包装在对象中。Float类型的对象包含一个类型为Float的字段。
此外，该类还提供了几个方法，用于将浮点转换为字符串，将字符串转换为浮点，以及处理浮点时有用的其他常量和方法。
