Thread: How convert sting name as an arrayList name?

I have a small problem that I am unsure on how to solve this.
I have a arrayList (arrayList_Chrom) with numbers/letters in it: 1, 2, 3 ...... 22, X, Y, M

Now I have made this for loop:

for (int x = 0; x > arrayList_Chrom.size(); x++) {
			String chrNumber = arrayList_Chrom.get(x);
}

Now I would like this when for example chrNumber = 1, I want arrayList_Chr1 to be used.
When chrNumber = 2, I want arrayList_Chr2 to be used.

But so far I am unable to do this.
I have tried making it a string name.

String right_arrayList = "arrayList_Chr" + chrNumber;

But then this code stops working, because right_arrayList is a String and not an ArrayList.
(what I know)

for (int k = 0; k < right_arrayList.size(); k++) {
				String value = right_arrayList.get(k); 
			}

How do I convert the String right_arrayList into an arrayList name?
