Hi ,
Can somebody throw some light on
Dynamic class loading and Dynamic Method loading ?
Thanks,

Mr. Ted Neward has several papers about this topic. They are really in depth discussion, and his results might surprise many Java Gurus.
Read them if you are interested. They might be more than you're asking for.

Hi,
Make a class with one method name "Add" with Two String arguments . And run the followng code and give runtime argument as your classname, it will invoke object for your class and call your "Add" method.

import java.lang.reflect.*;
class DynamicClass
{
public static void main(String[] args) throws Exception
{
String className = args[0];
Class c = Class.forName(className);
Object object = c.newInstance(); /* For Loading the Class Dynamically */

String s1 = new String("Java");
String s2 = new String("Dynamic Class");
Class param[] = {Class.forName("java.lang.String"), Class.forName("java.lang.String") };
Method m1 = c.getMethod("Add", param ); /* To call a Method 'Add' in that Class Dynamically */
Object paramObj[] = {s1,s2};
Object retObj = m1.invoke( object, paramObj );
}
}
