Hi, I have a situation where user can input the name of the files through html form (1 or 2 file, max is 2 files). Is it better to hold the file names in an array or in a vector? The problem is if i store it in an array, as the size of the array is 2. The element at location 2 in the array is null, which is leading to nullpointerexception when user submits only 1 file name. So, i am using vector instead of array to avoid this exception. Is this ok to do? If not, what's is the efficient way to do? Appreciate your input. Thanks,

Why don't you instantiate an array of the correct size (1 or 2 depending on the number of entered file names? Can you post some code?

As such u should not have any problem in using the arrays if the no. of elements are fixed. u shuld remember that array indexes starts from zero instead of 1 , so if u have used a array with the limit two say Array a; and latter u trying to access a element this will trey to acces the third element and thus will generate e exeption ArrayOutOfBoundsEexception,but in ur case it is null pointer esception so might be ur not able to put the data in the array b4 using it
