hey guys. OK so, I've been wondering this for a while now. my code is always so unnecessarily cluttered because I don't know how to do this, lol.

say I have a set of private class variables:

java Syntax (Toggle Plain Text)

private ArrayList row0 = new ArrayList<String>();
private ArrayList row1 = new ArrayList<String>();
// etc. all the way to 7 in this case

private ArrayList row0 = new ArrayList<String>(); private ArrayList row1 = new ArrayList<String>(); // etc. all the way to 7 in this case

Now i have a loop where i want to assign (for example), 8 periods or something to each array list as separate elements. I don't want to do this same code and repeat it 8 times for each list, like this:

java Syntax (Toggle Plain Text)

for (int i = 0; i < 7; i++) {
    row0.add(".");
    row1.add(".");
    // etc.
}

for (int i = 0; i < 7; i++) { row0.add("."); row1.add("."); // etc. }

instead I would like to be able do something like this....

java Syntax (Toggle Plain Text)

for (int i = 0; i < 8; i++) {
    for (int j = 0; j < 7; j++) {
        rowi.add(".");
    }
}

for (int i = 0; i < 8; i++) { for (int j = 0; j < 7; j++) { rowi.add("."); } }

how do I substitute that "i" in there though?

...or...
use nested arraylists
ArrayList<ArrayList<String>> rows
and access the inner ArrayLists, and their Strings in the usual way.

James, out of curiosity, isn't that the same thing as what Vernon suggested?

Oh, I was referring to where he said "Or make row an ArrayList of ArrayLists." I thought maybe there was some difference in syntax between how you did it and he did it or something. Nevermind.
