Yard yard = new Yard();

house.length = Integer.parseInt(JOptionPane.showInputDialog(null, "Enter the house length"));
house.width = Integer.parseInt(JOptionPane.showInputDialog(null, "Enter the house width"));

yard.length = Integer.parseInt(JOptionPane.showInputDialog(null, "Enter the yard length"));
yard.width = Integer.parseInt(JOptionPane.showInputDialog(null, "Enter the yard width"));
yard.area = house.area - (yard.length * yard.width);

// I don't understand the formula
// timecutting = yard.area / 2.3

JOptionPane.showMessageDialog(null, "Yard Length: "+yard.length +"\nYard width: "+yard.width +"\nYard Area: " +yard.area +"\nHouse Length: "+house.length +"\nHouse width: "+house.width +"\nHouse Area: " +house.area);
