Question

The statements in the following program are in incorrect order. Rearrange the statements so that it prompts the user to input the shape type (rectangle, circle, or cylinder), and the appropriate dimension of the shape. The program then outputs the following information about the shape: For a rectangle, it outputs the area and perimeter; for a circle, it outputs the area and circumference; and for a cylinder, it outputs the volume and surface area. After rearranging the statements, your program should be properly indented.

public class Ch4_PrExercise4

{

public static void main(String[] args)

{
System.out.print("Enter the shape type: (rectangle, " +" circle, cylinder) ");
shape = console.next();

System.out.println();
String shape

if (shape.compareTo("rectangle") == 0)
{
System.out.print("Enter the height of the cylinder: "); height = console.nextDouble();

System.out.println();
System.out.print("Enter the width of the rectangle: ");

width = console.nextDouble();

System.out.println();
System.out.printf("Area of the circle = %.2f%n", (PI * Math.pow(radius, 2.0)));
System.out.printf("Perimeter of the rectangle = %.2f%n", (2 * (length + width)));

}
double length;

double width;

else if (shape.compareTo("circle") == 0)

{
System.out.print("Enter the length of the rectangle: ");

length = console.nextDouble();;

System.out.println();
System.out.printf("Volume of the cylinder = %.2f%n", (PI * Math.pow(radius, 2.0)* height));
System.out.printf("Circumference of the circle: %.2f%n", (2 * PI * radius));

}
else if (shape.compareTo("cylinder") == 0)

{
double height;

double radius;

System.out.print("Enter the radius of the circle: "); radius = console.nextDouble();;

System.out.println();
System.out.print("Enter the radius of the base of " + "the cylinder: ");
radius = console.nextDouble();

System.out.println();
System.out.printf ("Area of the rectangle = %.2f%n", (length * width));
System.out.printf("Surface area of the cylinder: %.2f%n", (2 * PI * radius * height
+ 2 * PI * Math.pow(radius, 2.0)));
}
else
System.out.println("The program does not handle " + shape);
}
