Question

Write an application for a lawn-mowing service. The lawn-mowing season lasts for 20 weeks. The weekly fee for mowing a lot less than 400 square feet is $25. The fee for a lot that is 400 square feet or more, but fewer than 600 square feet, is $35 per week. The fee for a lot that is 600 square feet or over is $50 per week. Prompt the user for the length and width of a lawn, and then print the weekly mowing fee, as well as the 20-week seasonal fee. Save the class as Lawn.java.

Answer:

// library

import java.util.*;

// class definition

class Main

{// main method of the class

public static void main (String[] args) throws java.lang.Exception

{

   try{

    // object to read inputs

      Scanner scr=new Scanner(System.in);

      System.out.print("Enter length of lawn:");

      // read the length of lawn

      int length=scr.nextInt();

      System.out.print("Enter width of lawn:");

      // read the width of lawn

      int width=scr.nextInt();

      // find area of lawn

      int area=length*width;

      //if area is less than 400

      if(area<400)

      {// Weekly mowing fee

          System.out.println("Weekly mowing fee is:$25");

          // seasonal fee

          System.out.println("20-week seasonal fee is:$"+(25*20));

      }

      // if area >=400 and area <600

      else if(area>=400 && area<600)

      {

         // Weekly mowing fee

          System.out.println("Weekly mowing fee is:$35");

          // seasonal fee

          System.out.println("20-week seasonal fee is:$"+(35*20));

      }

      // if area >=600

      else if(area>=600)

      {

         // Weekly mowing fee

          System.out.println("Weekly mowing fee is:$50");

          // seasonal fee

          System.out.println("20-week seasonal fee is:$"+(50*20));

      }

   }catch(Exception ex){

       return;}

}

}

Explanation:

Read the length and width of lawn from user with the help of scanner object. Find the area of the lawn.If the area if less than 400 then Weekly mowing fee  is $25 and find the 20-week seasonal fee by multiply 25 with 20.If the area is greater than 400 and less than 600 then Weekly fee is $35 and seasonal fee  will be 35*20.if the area is greater than 600 then Weekly fee is $50 and seasonal fee will be 50*20.

Output:

Enter length of lawn:15                                                                                                    

Enter width of lawn:12                                                                                                    

Weekly mowing fee is:$25                                                                                                  

20-week seasonal fee is:$500
