Hidy ho all,

I just got an assignment where I have to find the Greatest Common denominator of 2 numbers that a user inputs.

My first idea on how to do this is to loop through both numbers to find which numbers between 0 and the inputed number, then store those numbers in a dynamic array, before finally comparing the two arrays to find which ones are equal.

Since I have no idea how many denomenators are in each array, I need to use a dynamic array. Now I'm coming to java from C++ so I know how to use vectors. My question is, are vectors able to be used in java? If so, where can I find more info on them?
