October 01, 2005 Rectangular Array Initialization | ||||
---|---|---|---|---|

| ||||

I've searched the archive and couldn't see a working solution for how to initialize a rectangular/multi-dimensional array. I get an ArrayBoundsError when attempting to access it. Here's my code: float[][] matrix = new float[][5]; for (int i = 0; i < 5; i++) { matrix[i].length = 5; } matrix[0][0] = 1f; matrix[1][1] = 1f; // ArrayBoundsError here However, if I change my code as follow, it works. matrix[0][0] = 1f; matrix[1].length = 5; matrix[1][1] = 1f; Haven't I already set the length of the array in my for loop earlier? What's going on? Thanks. |
