包路径：java.lang.reflect.Constructor
类名称：Constructor
方法名：getParameterTypes

Constructor.getParameterTypes介绍

[英]Returns an array of the Class objects associated with the parameter types of this constructor. If the constructor was declared with no parameters, an empty array will be returned.
[中]返回与此构造函数的参数类型关联的类对象数组。如果构造函数声明时没有参数，则将返回空数组。
