Coding conventions

Hi,

I'm almost finishing coding and checking what I wrote in the mean time. I have a simple question about declaring a reference. Sun says we should create object in the smallest scope needed for the object, that's ok but what about reference? Which one is more appropriate? Pay attention to "String [] myArray" declaration please.


Snippet one:



Snippet two:

It is the location of the the reference declaration that determines the scope of an object not where you create the object. In your example the second option is better as the variable is declared and only in the block of code that it is used in. This makes the code easier to understand.

Hi

The specs from sun

create object in the smallest scope needed for the object, that's ok but what about reference


is a line to follow not a must. You must decide where it fits and where in does not.
IMHO If the myArray is used in other palaces also then 1 otherwise 2.
