Explain in your own words how and why final variables are used. Illustrate your answer using the code below, explaining how it could be improved by the introduction of final variables. This code is intended to print the areas of 100 circles whose radius is input. The function, inputlnt, returns an integer input by the user. Note you are not required to explain or trace this code, just use it to illustrate points you make about final variables. public static void circles () { for (int i = 1; i <= 100; i ++) { int radius inputInt("What is the radius?"); = 3.14 * radius * radius; double area System.out.println(area); }
