Examine the following starter code. Use the comments and the code provided to complete the constructor and two methods in the RectangleStats class. import java.util.ArrayList; class RectangleStats { // Private instance variables // width is an ArrayList which will contain decimal values, length is an array which will contain decimal // values, and area is an array which will contain integer values. //code goes here for instance variables goes here //The constructor for the RectangleStats class takes an ArrayList and an array as parameters for // width and length, respectively. // code for constructor goes here // The calcRectangleArea() method calculates the area of rectangles using the length and width // assigned to the private instance variables and assigns the results to the area array of type int. // This method does not return anything. // code for the calcRectangleArea() method goes here // The printArea() method prints the values assigned to the area array using the most appropriate // type of loop. This method does not return anything. // code for the printArea() method goes here } // The RectangleStatsTesterClass assigns the width of two rectangles to an ArrayList and assigns the // length of two rectangles to an array. The calcRectangleArea() and printArea() methods are invoked to // calculate and print the area of the two rectangles. public class RectangleStatsTesterClass { public static void main(String[] args) { ArrayList dblWidth = new ArrayList(); dblWidth.add(5.2); dblWidth.add(9.3); double [ ] dblLength = {11.1, 4.7}; RectangleStats rectStats = new RectangleStats(dblWidth, dblLength); rectStats.calcRectangleArea(); rectStats.printArea(); } }
