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

Constructor.toString介绍

[英]Returns a string containing a concise, human-readable description of this constructor. The format of the string is:

1. modifiers (if any)
2. declaring class name
3. '('
4. parameter types, separated by ',' (if any)
5. ')'
6. 'throws' plus exception types, separated by ',' (if any)
   For example: public String(byte[],String) throws UnsupportedEncodingException
