import javax.swing.JOptionPane;
public class Lawn {


    public void Calcul(double leng, double wig){
        double squad = leng * wig;
        double weekCost, seasonCost;
        if(squad < 4000){
            weekCost = 25;
        } else if(squad >= 4000 & squad < 6000){
            weekCost = 35;
        } else{
            weekCost = 50;
        }
        seasonCost = weekCost * 20;
        String rez = "The weekly lawn mowing fee is: " + weekCost + "\nThe seasonal lawn mowing fee is: " + seasonCost;
        JOptionPane.showMessageDialog(null, rez);
    }

    public static void main(String[] args) {

        Lawn law = new Lawn();

        String lenghtS = JOptionPane.showInputDialog("Enter");
        double lenght = Double.parseDouble(lenghtS);

        String widthS = JOptionPane.showInputDialog("Enter");
        double width = Double.parseDouble(widthS);

        law.Calcul(lenght, width);

    }
