隐式等待(implicit)隐式等待是一种设置全局查找页面元素等待时间的方法。在此等待时间内，如果未找到指定元素，则会抛出异常。设置隐式等待只需一次，其语法如下：显示等待(explicit)显式等待是获取页面元素超时设置中使用频率最高的方法。其原理是通过设置最大等待时间和周期时间，按照周期时间检测是否出现等...

This section describes type casting supported in Java: up casting (widening reference conversion) and down casting (narrowing reference conversion). Cast operation can be written explicitly with the cast operator (T), or implicitly with no operator.
