包路径：java.lang.Character
类名称：Character
方法名：valueOf

Character.valueOf介绍

[英]Returns a Character instance for the char value passed.

If it is not necessary to get a new Character 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]返回传递的字符值的字符实例。
如果不需要获取新的Character实例，建议使用此方法而不是构造函数，因为它会维护实例缓存，从而提高性能。
