9.3 Aggregate Two-Dimensional Array Operations

As with single-dimensional arrays, Java does not support aggregate opera-

tions on multidimensional arrays. For example, you cannot print the con-

tents of an array using only the array name. Instead, you need to process

each element individually.

9.3.1 Processing All the Elements of a Two-Dimensional Array

To process all the elements of a two-dimensional array, we use nested for

loops that access and process each element individually. Often, the most

logical way to process all elements is in row order, and within each row, in

column order. W
