    2d array quick question

    how to loop though 2d-array horizontally from left to right.
    so when i loop though like 1,2,3,4,5,6,7,8

    i just want to make sure this loop is doing what i think it does?


    Code:
    int array[][] = {{1,2,3,4},
                 {5, 6, 7, 8}};


for (int y= 0; y< array.length; y++) { 
    for (int x= 0; x < array[y].length; x++) { 
           array[y][x] == 2
			}
		}

      Apart from line 7 missing a semicolon at the end, it should be fine. To make sure it works you could however have just put a line like [code=java]System.out.prin tln(array[y][x]);[/code] rather than the current line 7 (or before it) and check whether the output is as expected.

              It will access the elements in the order 1, 2, 3, 4 and then 5, 6, 7, 8 if that's what you mean, yes.
