包含获得各种集合对象的常用方法的泛型工具类。如果要获得一个 {@code Map<String, String>} 的对象，可以通过下面的方式实现：

* {@literal Map<String, String> map = GenericUtils.getMap() }。但是不能直接作为参数使用，例如有这样一个方法：

* {@literal setInfo(Map<String, String>)}，不能直接这样调用：<s>

* <code>setInfo(GenericUtils.getMap())</code></s>-Generic tools commonly used method to get various collection object. If you want to get a {@ code Map <String, String> } Object, by way of the following:* {@ literal Map <String, String> map = GenericUtils.getMap () }. But can not be directly used as a parameter, such as a:* {@ literal setInfo (Map <String, String> )}, Can not be directly called like this: <s>* <code>setInfo(GenericUtils.getMap())</code></s>
