RE: [Eap-features] introduce variable : encourage use of interface

[Nemec, Richard]

What are your reasons, Alain?

(I see, two reasons but I wouldn't put either of them as a general rule.)

If you want to use the variable just locally, why not allow to use the whole

ArrayList functionality?

If you want to pass it in an List argument, you just pass it as ArrayList.

 

I found it being much better coding habit to have the variable of the same

type as the value (if possible). And I'm sure there are more "theory-founded"

reasonings for that.

Subject: [Eap-features] introduce variable : encourage use of interface

When using "Introduce Variable" on  

    .

    new ArrayList ();

 

you get

 

   ArrayList arrayList = new ArrayList ();

 

 

Most of the time, though, you should use

   .

   List arrayList = new ArrayList ();

 

 

 

"Introduce Variable" should allow the user to choose it's target type.
