flow condition

i wonder if it makes sense to refactor from this:


public void someMethod(SomeClass someObject) {
    if(someObject != null){
        do something ...
    }
}
to this:
public void someMethod(SomeClass someObject) {
    if(someObject == null) return;
    do something ...
}

When XP says "go for the simplest possible design", what does that mean?
1. Simplest possible design to IMPLEMENT?
1. Simplest possible design to UNDERSTAND LATER?

An thread discuss how far should we go. Seen most people agree what should be done is "Simplest possible design to TEST and IMPLEMENT"

High level software design discussion

A nice table:

Do	Don't
1. Focus on interfaces.	2. Be worried about the implementation.
3. Mention semantic contract using interfaces.	4. Let subtypes break this semantic contract of their parent types.
5. Service decoupling using interfaces.	6. Be coupled with specific concrete implementation.
7. Family extension using interfaces.	8. Break the family relationship using concrete implementation.
9. Establish a family rule by abstract classes.	10. Impose your own rule through concrete classes.
11. Let interfaces answer all "what" about the system.	12. Forget to mention "how" are you answering all "what" from interfaces.
