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();
