Explanation / Answer

Faults in the code:-

1. Variable 'radius' has been declared multiple times in the same method block.

Below are the declarations:

Line 11 : Random radius = new Random();

Line 26 : String radius = scan.nextInt();

Line 27 : int radius = Integer.parseInt(radius);

Solution : Variable 'radius' should be of double type as it can be a floating values.

double radius;

2. Since radius is of double type variable, scanner should read double value from the input.

Solution : double radius = scan.nextDouble();

Fixed Asgn1.java is here.

-------------------------

package assignment;

import java.util.Scanner;

public class Asgn1 {

public static void main(String[] args) {

Scanner scan = new Scanner(System.in);

System.out.println("Enter the top-left coordinates for the rectangular portion: ");

String x11 = scan.next();

int x1 = Integer.parseInt(x11);

String y11 = scan.next();

int y1 = Integer.parseInt(y11);

System.out.println("Enter the bottom-right coordinates for the rectangular portion: ");

String x22 = scan.next();

int x2 = Integer.parseInt(x22);

String y22 = scan.next();

int y2 = Integer.parseInt(y22);

System.out.println("Enter the radius of the circular portion of the field: ");

double radius = scan.nextDouble();

int side1 = x2 - x1;

int side2 = y1 - y2;

int perimeter = 2*side1 + 2*side2;

double circumference = 2 * Math.PI * radius;

double fenceLength = perimeter - 2 * radius + 3.0 / 4 * circumference;

System.out.println("You will need " + fenceLength + "meters of fence around this field.");

int rectangleArea = side1 * side2;

double circleArea = Math.PI * radius * radius ;

double area = rectangleArea + 3.0 / 4 * circleArea;

System.out.println("You have to cover " + area + "square meters with grass.");

}

}
