Multi-Dimensional Arrays
We can expand the whole idea of arrays to multiple dimensions, beyond one or two dimensions. Read these sections to see how this is done.
Array Initializers
It is possible to use an initializer with a multidimensional array. For instance, the following examples create several small arrays and initialize
their elements:
The first of these declarations creates a 2 ⇥ 3 array of integers. The second
example creates a 2 ⇥ 2 array of characters, and the third example creates
an array of double consisting of three rows, each of which has a different
number of elements. The first row contains three elements, the second
contains two elements, and the last row contains four elements. As this
last example shows, the rows in a multidimensional array don't all have
to have the same length.
Using initializers, as in these examples, is feasible only for relatively
small arrays. To see why, just imagine what the initializer expression
would be for our three-dimensional rainfall array. It would require
4,160 = 10 ⇥ 13 ⇥ 32 zeroes, separated by commas!
