double cost = 0;
double used = 0;
Scanner inpScan = new Scanner(System.in);

System.out.print("Enter cost per kilowatt-hour in cents: ");
cost = Double.parseDouble(inpScan.nextLine());

System.out.print("Enter kilowatt-hours used per year: ");
used = Double.parseDouble(inpScan.nextLine());

System.out.format("Annual cost: %.4f%n", cost*used*0.01);

inpScan.close();
