java - How to display output in servlet when invoking a method dynamically -

I am trying to load a class dynamically and calling it one of its own method from Servlet I am

In my service I have the following code:

  PrintWriter out = response.getWriter (); {Class & lt;? & Gt; Obj = Class.forName (myclassName); Method method = obj.getClass (). GetMethod (myMethodName); String Return Value = (string) method.invoke (obj, null); Out.println (returnValue); } Hold (exception E) {}   
 and in my class:  
  public class student class {public string index () {return "it is From the student class "; }}   
 The problem is that when I run my application it does not show anything  it is from the student class  to get the output as Hopefully, that's basically returning the class of the  index  method.  
 Can you please tell me how to solve this problem?   
 
 
 Your  incoming  usage is incorrect:  
 < Code> class & lt ;? & Gt; Obj = Class.forName (myclassName); // It returns a class, not an example method method = obj.getClass (). GetMethod (myMethodName); String Return Value = (string) method.invoke (obj, null);   
 Fair use will be something like this:  
  class   
.
