 So now that I can create multi-dimensional arrays, what happens if I want to populate it on the fly? I use the exact same mentality as before. I start with my double square brackets to indicate that this has got a width and a height to it. Two-dimensional array, distance. And just like we learned with a single-dimensional array, I can do my curly braces. Now what's happening here is again, this is good to kind of read it kind of right to left. I'm creating a collection of a collection of integers. So what this does is now that I've got this first curly brace right here, that's this guy. I'm now dealing with him right now. If I want to start building this on the fly, what happens is now I include curly braces for sort of my collection of a collection. And for our sake, if we look sort of on this table here, I would just pass these values in. So 0, 9, 8, 3, 7, 8, 7, 7, 14. Now we'll do all of them. You can skip ahead if you'd like. 375, 967, 1087. Now one thing I'm going to do is I'm going to scroll just a hair over. Because how do I end this? Well, I end it with a curly brace. But the big thing I want to focus in on is that I put a comma here. Just like I would inside of my array, just like any normal separation of my elements, I put a comma in here to indicate that there is going to be another value. There's going to be another entry in here. And for my sake, I would then in turn come in and say 9, 8, 3, 0, 2, 14, 2, 17, 63, 17, 23, 23, 18, 42. I'd close my curly brace. And then I would include, wrong color, I would include another comma. And I'd continue to go down until I reached the last element in my array. 87, 42, 27, 10, 87, 39, 0. Now notice I don't need to put actually a comma here. I can if I want, but I just as a rule of thumb, don't put a comma in afterwards. Only because it's sort of already in place. I'm saying this is the ending point, so I don't want that comma in there. Now what this allows me to do is, again, this allows me to populate data on the fly, just like as if it was a normal, traditional, single-dimensional array.
