Two-Dimensional Arrays with Rows of Different Lengths
The manner in which multidimensional arrays are represented makes them quite flexible. In fact, the lengths of the rows in array b are not required to be the same. For example,
int[][] b = { { 1, 2 }, { 3, 4, 5 } };
creates integer array b with two elements (determined by the number of nested array initializers) that represent the rows of the two-dimensional array. Each element of b is a reference to a one-dimensional array of int variables. The int array for row 0 is a one-dimensional array with two elements (1 and 2), and the int array for row 1 is a one-dimensional array with three elements (3, 4 and 5).
