Input is from a file called num1.in Input consists of 4 doubles representing the radii of 4 circles. You are to make an array of circles and then print out the contents of the array in reverse. Output should be the radius followed by the circumference, one per line. So the output looks like this:

3.5 21.991148575128552 0.8 5.026548245743669 2.15 13.50884841043611 0.7 4.39822971502571

Circle.java

public class Circle { //attribute private double radius; //constructors public Circle() {radius=0.0; } public Circle(double r) {radius=r; } //accessors public double getRadius() { return radius; } //mutators public void setRadius(double r) { radius = r; } //methods public double circumference() { return 2*Math.PI*radius; } public double area() { return Math.PI*radius* radius; } }

Lab5Num2.java

public class Lab5Num2 {

public static void main(String[] args) { //declare input file. DO this exactly as you did in netBeans. Try/Catch. Don't forget imports //create (declare) an array that can hold Circle objects //input 4 Circle objects into the array //DO THE REST AFTER YOU HAVE CREATED THE ARRAY //output the radius and circumference of each member of the array starting with the LAST ONE } }
