P.s: please besides the code, also include a screenshot of code, and the output to confirm code doesn't get edited out and the output satisfies the problem!!

SodaCanTester.java

/** A class to calculate the area of several SodaCans */ public class SodaCanTester { /** Calculates the average area in an array list of SodaCans @param SodaCanArray the SodaCans @return the average area of SodaCanArray */ private static double averageArea(Measurable[] sodaCanArray) { //-----------Start below here. To do: approximate lines of code = 4 // get the measure of area from all sodaCan objects in the array, add them up and // compute the average. return the average //-----------------End here. Please do not remove this comment. Reminder: no changes outside the todo regions. } public static void main(String[] args) { SodaCan[] sodaCans = new SodaCan[4]; sodaCans[0] = new SodaCan(2, 3); sodaCans[1] = new SodaCan(3, 3); sodaCans[2] = new SodaCan(5, 7); sodaCans[3] = new SodaCan(1, 1); System.out.printf("The average area is: %10.2f", averageArea(sodaCans)); System.out.println(" Expected: The average area is: 186.92"); } }

SodaCan.java

/** Class to get surface area and volume of a soda can. */ public class SodaCan implements Measurable { private double height; private double radius; /** Initializes a can with given height and radius. @param height the height @param radius the radius */ public SodaCan(double height, double radius) { this.height = height; this.radius = radius; } /** Calculates the surface area of the soda can. @return the surface area of the soda can */ public double getSurfaceArea() { return 2 * Math.PI * radius * (radius + height); } /** Calculates the volume of the soda can. @return the volume of the soda can */ public double getVolume() { return Math.PI * radius * radius * height; } /** Returns the area of the soda can. @return the area of the soda can */ //-----------Start below here. To do: approximate lines of code = 2 // write a method that correctly implements the Measurable interface // The method should return the surface area of the sodaCan object //-----------------End here.

Measurable.java

public interface Measurable { double getMeasure(); /** Computes the smallest of the measures of the given objects. @param objects an array of Measurable objects @return the object with the smallest measure, null if array is empty */ static Measurable smallest(Measurable[] objects) { if (objects.length == 0) { return null; } Measurable min = objects[0]; for (Measurable obj : objects) { if (obj.getMeasure() max.getMeasure()) { max = obj; } } return max; } }

Double check all works fine thank you :)

Purpose: practice implementing an interface (Measurable) and writing a general method that computes the average area of an array of SodaCan objects See the following files: * SodaCanTester.java (has todo) * SodaCan.java (has todo) * Measurable.java Approximate total lines of code required: 6
