Row-major order a, a, 2 a 3 ar an 223 az azza33 Column-major order @ 1 a apa 231 232 272 13 23 33 1 In Java, 2D arrays are stored in memory in row-major order, however, a 2D array can be traversed in either order. One question is, if you write a doubly-nested for loop to traverse and initialize a 2D array, something like this, which is in row-major traversal (make sure that you can see that this is the case by looking at the loop indices and convince yourself that it matches the order in the figure above): public static void init(double x[][]) { int rows = x. length; int cols = x[0].length; double sum = 0.0; for (int i = 0; i
