My diagram was not good Idea. :
The diagram represents:
Class B is the interface.
Class A implements the interface.
than,
Class A - - - - - - |> Class B.
I say :
The class B is a realization of Class A
OR
The class A is a realization of Class B

The Relationships is of Realization (with arrow closed).
My doubt is. I say:
The class B is a realization of Class A
OR
The class A is a realization of Class B
______________ _____________ | | | | | | | | | | | | | Class A | - - - - - - -|> | Class B | | | | | | | | | |____________| |____________

Hi,
I need the help. How I do dynamic casting using reflection ? I must to pass only the class name.
My code is it:
...
Class classe = null;
// father of TransactionProcessor
Module md = null;
Method method = null;
try{
classe = Class.forName(classname);
// getInstnce is the SingleTon class and return TransactionProcessor type
method = classe.getMethod("getInstance", null);
// md = ( TransactionProcessor ) method.invoke(null,null); I CANT DO IT because it is a code generic.
md = ( ??? ) method.invoke(null,null);
md.run();
}catch(){};
I know that I can get the type of return using:
method.getReturnType().getName();
,but I can do the dynamica casting ?
Thanks

I think that this diagram is better (see http://www.zanthan.com/itymbi/archives/000596.html
The doubt is: The method nextId() is of object Comment or IDGen.

HI, I have a Doubt about Sequence Diagram.
Imagine this 2 objetcts, that pertence Sequence Diagram below.

ObjA ObjB
event ----------------> * --------methodX()---------> *
* *
* *
* *
* *
* *

The methodX() is a message.

The question is: The methodX() is a method of ObjA or ObjB ?

Class ObjA{
...
ObjB objB = new ObjB();
objB.methodX();
...
}


or

Class ObjB{
...
ObjA objA = new ObjA();
objA.methodX();
...
}
