类名称：Validate
方法名：validState

Validate.validState介绍

[英]Validate the stateful predicate is true for the given object and return the object; otherwise throw an exception with the specified message.
String value = Validate.validState(someString, s -> s.length() == 0, "must be blank got: %s", someString);
[中]验证给定对象的有状态谓词是否为真，并返回该对象；否则，将使用指定的消息引发异常。
字符串值=验证。validState（someString，s->s.length（）==0，“必须为空，获取：%s”，someString）；
