    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++.
