本文整理了Java中java.lang.Byte.valueOf()方法的一些代码示例，展示了Byte.valueOf()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。Byte.valueOf()方法的具体详情如下：
包路径：java.lang.Byte
类名称：Byte
方法名：valueOf

Byte.valueOf介绍

[英]Returns a Byte instance for the specified byte value.

If it is not necessary to get a new Byte instance, it is recommended to use this method instead of the constructor, since it maintains a cache of instances which may result in better performance.
[中]返回指定字节值的字节实例。
如果不需要获取新的字节实例，建议使用此方法而不是构造函数，因为它可以维护实例缓存，从而提高性能。
