You cannot. You must declare the array outside the loop. This may seem strange at first but what if the condition for the loop to run even once is never met? How could you possibly then access an array which was never even created?

You cannot. Java uses block scope, so variables declared within any block (such as a loop) are not accessible from outside. You'll need to assign them to something that has an outer scope.
