Question

I need to create a java program to calculate the costs and time associated with painting only the walls in the room provide the length, width and height (in feet) of a room along with the total square footage of doors and windows that are not painted one gallon of paint will cover 150 square feet and takes 60 minutes to apply using whole gallons therefore any fractional amount calculated must be rounded up to the next whole gallon, i.e. a calculated 2.4 gallons would be rounded to 3. The company also charges $15.00 per hour for labor. Finally provide the cost per gallon for the paint he is using. The eventual program will display Number of gallons required Total cost of the paint Total time needed to paint the room and Total labor cost.

Test case: For a room 10 ft x 10 ft x 8 ft with 40 sq ft of window/door space.

Paint cost of $15/gal

Number of gallons required = 2

Total cost of the paint = $30.00

Total time needed to paint the room = 1 hour 52 min

Total labor cost = $28.00

Document the following areas: Determine the primary class(es) and hence the object(s) Determine the methods Define the interface Determine instance variables Implement the methods Create the final class Test and debug as necessary Remember

Explanation / Answer

import java.util.*;

import java.lang.*;

import java.io.*;

class paint

{

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

{

double height,width,length,window_area;

height=10.0;

width=10.0;

length=8.0;

window_area=40.0;

double total_area=height*width+width*length+height*length+window_area;//calculatin/g total area

double gal=total_area/150.0;//finding required gal

double cost=gal*15.0;//finding cost

int gallon=Math.round(gal);//rounding the gallon

int time=gallon*60;//calculating time

int hr=time/60;//Hour

int min=time%60;//minute

double charge=hr*15.0;//labor cost

//Printing all the outputs

System.out.println("Height:"+height+"Width:"+width+"Length:"+length+"Window Area:"+window_area);

System.out.println("No. of Gallon Required:"+gallon);

System.out.println("Cost of Paint:"+cost);

System.out.println("Time:"+hr+"hr"+min+"min");

System.out.println("Labor Cost:"+charge);

}

}
