Hello,

I'm trying to create a class that can instantiate arrays at runtime by giving each array a "name" created by the createtempobjectname() method. I'm having trouble making this program run. I would also like to see how I could access specific objects that were created during runtime and accessing those arrays by either changing value or accessing them. This is my mess so far, which compiles but gets a runtime exception.

import java.lang.reflect.Array;

public class arrays { private static String temp; public static int name = 0; public static Object o; public static Class c;

    public static void main(String... args)
    {
        assignobjectname();
        //getclassname();//this is supposed to get the name of the object and somehow 
                         //allow the arrays to become updated using more code?
    }
    public static void getclassname()
    {
        String s = c.getName();
        System.out.println(s);
    }
    public static void assignobjectname()//this creates the object by the name returned
    {                                    //createtempobjectname()
         try
         {
          String object = createtempobjectname();
            c = Class.forName(object);
            o = Array.newInstance(c, 20);
         }
         catch (ClassNotFoundException exception)
         {
            exception.printStackTrace();
         }
    }
    public static String createtempobjectname()
    {
        name++;
        temp = Integer.toString(name);

        return temp;
    }

}
