C# type delegates in java

Well - if you like me ever wanted something much like the C# delegate or a pointer to a method, in java - this might be for you. Its not quite there, but this is as close as I could come... Written in notepad on a cloudy evening..

import java.lang.reflect.*;

public class Test
{


 public void objectCallback(String parameter)
 {
  System.out.println("objectCallback("+parameter+")");
 }

 public static void instanceCallback(String parameter)
 {
  System.out.println("instanceCallback("+parameter+")");
 }

 public void add(int val1, int val2, Delegate delegate)
 {
  int result = val1 + val2;
  try {
   delegate.delegate(new Object[] { String.valueOf(result) });
  } catch (Exception e) {
   e.printStackTrace();
  }
 }


 public static void main(String[] args) {
  System.out.println("Test start");
  Test test = new Test();
  test.add(3, 3, new Delegate(test, "objectCallback"));
  test.add(3, 3, new Delegate(Test.class, "instanceCallback"));
  System.out.println("Test end");
 }  


 public static class Delegate
 {
  private String methodName;
  private Class clazz;
  private Object object;
  
  public Delegate(Class clazz, String methodName)
  {
   this.clazz = clazz;
   this.methodName = methodName;
  }

  public Delegate(Object obj, String methodName)
  {
   this.object = obj;
   this.methodName = methodName;
  }

  public void delegate(Object[] args) throws NoSuchMethodException, InvocationTargetException, IllegalAccessException
  {
   if (object != null) {
    Class objClass = object.getClass();
    Method method = objClass.getMethod(methodName, mapArgs(args));
    method.invoke(object, args);
   } else if (clazz != null) {
    Method method = clazz.getDeclaredMethod(methodName, mapArgs(args));
    if (Modifier.isStatic(method.getModifiers())) 
     method.invoke(null, args);
    else
     throw new NoSuchMethodException("Method "+method+" is not static on class "+clazz);
   }
  }
  
  private final static Class[] mapArgs(Object[] args)
  {
   if (args != null) {
    Class[] cArray = new Class[args.length];
    for (int i=0;i<args.length;i++) {
     if (args[i] !=  null)
      cArray[i] = args[i].getClass();
     else
      cArray[i] = Object.class;
    }
    return cArray;
   }
   return null;
  }

 }

}
