Dynamically set values of ArrayList to variables

Question

I'm writing a program that has an ArrayList<String> s. Is there a way to get each value from the ArrayList and set them to separate variables? For example:

String s0 = s.get(0);
String s1 = s.get(1);
String s2 = s.get(2);
.
.
.
String sn = s.get(n);

I will know what 'n' is but it will change based on user input. I just don't know how to/if I can dynamically create variables based on some number n. Any help would be much appreciated!

How would you reference a dynamically created variable? It wouldn't exist at compile time. — Mike Strobel

Why would you want to do this? Just get the value from the arraylist when you need it. What are you actually trying to acccomplish? — Andrew

I'm trying to calculate the number of differences between each combination of strings in my ArrayList and put those in a 2d array. For example s1 = AAA s2 = ABA s3 = ABC s1s2 = 1 s1s3 = 2 s2s3 = 1 and then put those values into a difference matrix. I guess I can just compare the values as I fill the matrix based on i and j since [0][0] would be s1s1 [0][1] would be s1s2 ect. I just didn't know if there was an easier way — Ryan Sayles

You cannot. This is what arrays (and ArrayLists) are for!
