I'm stuck on this computer science program can someone help me please, thanks in advance

arguments, and display them in an appropriate message on the screen. 4. Paint Job Estimator A painting company has determined that for every 115 square feet of wall space, one gallon of paint and eight hours of labor will be required. The company charges $18.00 per hour for labor. Write a program that allows the user to enter the number of rooms to be painted and the price of the paint per gallon. It should also ask for the square feet of wall space in each room. The program should have methods that return the following data: The number of gallons of paint required . The hours of labor required

OUTPUT:

Enter the number of rooms: 2
Enter the price of paint per gallon: 1054
Room No: 1
Enter wall Space: 580
Room No: 2
Enter wall Space: 460
Total Wall Space: 1040.0
Labor cost: $1,302.26
Paint cost: $9,531.83
The totalcost of the paint job is: $10,834.09
