And the reason why this solves the problem is . . .?
I don't mean to sound harsh, but when you answer a beginning-level question
without explaining it, you're not really helping the person to learn. The
reason may be obvious to you, but if it were as obvious to the asker, they
wouldn't have had to ask in the first place.
So, the reason that you get the "variable may not have been initialized"
message is that if an exception happens in the try block before the code
that populates the array, control is transferred to the catch block and then
if there is any access to the array after that, it won't have been
initialized. The compiler checks to see if there is any possible path of
execution that can get to a usage of a variable without going through an
assignment to that variable. If even one exists, it will give the error
message (which is why it uses the word "may", meaning "possibly").
Initializing the variable on the declaration, even to null, assures that
there is no path that leaves it uninitialized.

Subject: Re: accessing array initialized in a try statement
Very well, put an initialize statement before try-catch block.
For example
Vector v = null;
try
{
populate v here
}
catch()
{}
Now you can access your Vector v without the initialization error.
