// Import the Scanner class

public class WallArea
{
   public static void main(String[] args)
   {
      // Declare a scanner

      // Prompt for and read the width and height
      // and the number of windows

      // Compute the area of the wall without the windows

// Declare a scanner

Scanner in = new Scanner(System.in);

// Prompt for and read the width and height

System.out.print("Wall width:");

double width=in.nextDouble();

System.out.print("Wall height:");

double height=in.nextDouble();

// and the number of windows

System.out.print("Number of windows:");

int windows=in.nextInt();

// Compute the area of the wall without the windows

double area=width*height;

System.out.println("Area: " + area);
