Android™ How to Program, Second Edition

Calculating the Values to Store in an Array

The application in Fig. E.4 creates a 10-element array and assigns to each element one of the even integers from 2 to 20 (2, 4, 6,..., 20). Then the application displays the array in tabular format. The for statement at lines 12–13 calculates an array element’s value by multiplying the current value of the control variable counter by 2, then adding 2.
