Problems with ArrayList

Hi!

I'm wondering what this line does:

Code:

---

ArrayList[][] grid = new ArrayList[100][50];

water.grid[h][v].push_back(&i);

// c and d are calculated values.
ArrayList al = this.grid[c][d];

---

What will

Code:

---

al

---

hold exactly?

Later on this is done:

Code:

---

int n = al.size();
for (int q = 0; q < n; q++) {
  int j = ((Integer)al.get(q)).intValue();
 
  ........

---

Shouldn't al.size() always just be 1 or am I missing something here?

Please help

Well, It doesn't look like Java, rather C++.
