reflecting: Creating a new object of a reflected class via code

Hello. I am trying to input the name of a class that I have imported already, and can instantiate regularly, such as ‘myClass inst = new myClass(‘foo’);’ and create a new instance-object of that class. The code below illustrates my question more specifically:

import java.lang.reflect.*;
import java.io.*;

public class reflecting1
{
   public reflecting1()
   {

        BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));
        System.out.print("Input the name? n");

        try
        {
           typed = reader.readLine();
        } catch (Exception e) {}

       try
       {
         Constructor con = (typed.class).getConstructor(String.class);

         Object obj = con.newInstance("Hello World!");
         Method methd = (typed.class).getMethod("hashCode");

         System.out.println(obj);

         int hash = methd.invoke(obj);
         System.out.println(hash + "");

        } catch (Exception ee) {
        System.err.println("Class not created.");

        }

    }

}

import java.lang.reflect.*;<br /><br />import java.io.*;</p><br /><p>public class reflecting1<br /><br />{<br /><br /> public reflecting1()<br /><br /> {</p><br /><p> BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));<br /><br /> System.out.print(“Input the name? n”);</p><br /><p> try<br /><br /> {<br /><br /> typed = reader.readLine();<br /><br /> } catch (Exception e) {}</p><br /><p> try<br /><br /> {<br /><br /> Constructor con = (typed.class).getConstructor(String.class);</p><br /><p> Object obj = con.newInstance(“Hello World!”);<br /><br /> Method methd = (typed.class).getMethod(“hashCode”);</p><br /><p> System.out.println(obj);</p><br /><p> int hash = methd.invoke(obj);<br /><br /> System.out.println(hash + “”);</p><br /><p> } catch (Exception ee) {<br /><br /> System.err.println(“Class not created.”);</p><br /><p> }</p><br /><p> }</p><br /><p>}

When the input of the above program is: ‘String’

Why is the output not:

“

Hello World!

-969099747

“

and I tried:

public class reflecting2

        BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));

           typed = reader.readLine();
        } catch (Exception e) {}

       try
       {
         Class newC = Class.nameOf(typed);
         Constructor con = (typed.class).getConstructor(String.class);

         Object obj = con.newInstance("Hello World!");
         Method methd = (typed.class).getMethod("hashCode");

         System.out.println(obj);

         int hash = methd.invoke(obj);
         System.out.println(hash + "");

        } catch (Exception ee) {
        System.err.println("Class not created.");

        }

    }

}

but still didn’t work.. does anyone know how to make this work?
