ok so if i want to make it clear because i don't think i have completely understood you
you're telling me to make an array of missiles make it like the borders array so it only draws them where they should appear
lets say
0 0 1 (or nulls)                                                                                               1 1 1
0 1 0                                                                                                            0 1 0
1 0 0 .. if this is what you meant how do i check collision here if lets the borders are  0 0 0 then i would stop drawing at the 1 in the center? just to clarify

I've been working on a dropdown shooter game i've been working on this for a long time now i have not been able to solve one problem that's stopping me from proggressing

my code : http://pastebin.java-gaming.org/e58cc3f9c3f

I know its too long but i cant really ask one part of it as it wouldnt make sense
i have an array of tiles the map which makes up the map each tile location ad rectangle is represented in borders[] array
and i have the bullet rectangle which changes continuesly
what i want is if bullet collides with any of the tiles it should dissappear you can see from my messy code that i've tried numerous ways

and any advice on how to improve my code would be greatly appreciated

and if i get to fix this i would share my game and maybe show people how easy it is to make one
any help is greatly appreciated since this is bugging me for days now
thanks in advance
