How do I simulate "Foo foo = new Foo()" using reflection?

Question

This works:
void invokeAMethod(Object object, Method method) {
          try {
               method.invoke(object, null);
          } catch (IllegalArgumentException e) {
               e.printStackTrace();
          } catch (IllegalAccessException e) {
               e.printStackTrace();
          } catch (InvocationTargetException e) {
               e.printStackTrace();
     }however, this doesn't:
void invokeAMethod(Object object, Method method) {
          try {
               method.invoke(Class.forName("test.reflection.sandbox.Person"), null);
          } catch (IllegalArgumentException e) {
               e.printStackTrace();
          } catch (IllegalAccessException e) {
               e.printStackTrace();
          } catch (InvocationTargetException e) {
               e.printStackTrace();
          } catch (ClassNotFoundException e) {
               // TODO Auto-generated catch block
               e.printStackTrace();
//java.lang.IllegalArgumentException: object is not an instance of declaring classThis doesn't work either:
private void testGetter(Method getter) {
          try {
               Object myclass = Class.forName(getter.getDeclaringClass().toString());
               getter.invoke(myclass, new Object[]{});
          } catch (IllegalArgumentException e) {
               e.printStackTrace();
          } catch (IllegalAccessException e) {
               e.printStackTrace();
          } catch (InvocationTargetException e) {
               e.printStackTrace();
          } catch (ClassNotFoundException e) {
               e.printStackTrace();
//java.lang.ClassNotFoundException: class test.reflection.sandbox.PersonDoes anyone know how to solve this, please?

Answer 1

... and the class the method is declared in isn't necessarily the type of the object you want to call it on. You might want to call it on a derived class.
But then what the point of creating a new object and calling a method and then throwing the object away is I don't actually know. Surely you would already have the object?
