Two-Dimensional Array Example: Displaying Element Values

Figure 7.17 demonstrates initializing two-dimensional arrays with array initializers, and using nested for loops to traverse the arrays (i.e., manipulate every element of each array). Class InitArray’s main declares two arrays. The declaration of array1 (line 9) uses nested array initializers of the same length to initialize the first row to the values 1, 2 and 3, and the second row to the values 4, 5 and 6. The declaration of array2 (line 10) uses nested initializers of different lengths. In this case, the first row is initialized to two elements with the values 1 and 2, respectively. The second row is initialized to one element with the value 3. The third row is initialized to three ...
