Problem Statement:

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 $20.00 per hour for labor.

Develop a Java program, where

• data are provided (under Input Requirements) to the program,
• computations (under Processing) are performed using the data (under Input Requirements),
• results of the processing (under Output Requirements) are displayed

Input Requirements:

Set up the data for the following as named constants for one gallon of paint:

• 115 square feet of wall space
• eight hours of labor

Also, set up a named constant for the following:

• $20.00 per hour for labor

Enter the following input data at the keyboard:

• The square feet of wall space to be painted
• The price of the paint per gallon

Processing:

Your program is to perform the following calculations:

• The number of gallons of paint required
• The hours of labor required
• The cost of the paint
• The labor charges
• The total cost of the paint job

Output Requirements:

• The square feet of wall space to be painted
• The price of the paint per gallon
• The number of gallons of paint required
• The hours of labor required
• The cost of the paint
• The labor charges
• The total cost of the paint job

NOTE: Precede each of the above output data items with an appropriate message.

For instance, if the user entered 1150 square feet of wall space during the inputting, then

display a message like the following, along with the suare footage: 1150 square feet of wall space needs to be painted.

Extra-Credit (5 points): Display the data that is of type double using 2 digits after the decimal point.

Refer to section 2.3 and/or section 2.4 on how to format your output data with digits after the decimal point.

======================================================================

Use MS-Word to create a file to contain the text of your solution (in Java).

Save the file you created using MS-Word to your computer (or flash drive).

You need to set up a Java program that is complete and workable. For your solution to be complete, you must

• provide the above input data
• set up correct formulas to process the input data, arriving at the output data
• provide the output data to the user

For your solution to be workable,

• Your solution should be free of any type of errors (syntax, run-time, logic)
• you may want to develop an algorithm first, using pseudocode
• you do NOT need to turn in any algorithm

Instructions on documenting your solutions:

• Prior to the start of your solution, include a paragraph, explaining what is being accomplished. (3 points)

For examples on how to do documentation, check out section 2.4 in the text

Within your solution, include the following 3 sections:

• • Input Data: document variables used to hold input data (2 points)
  • Output Data: document variables used to hold output data (2 points)
  • Processing: document the formulas/equations you set up as part of your processing (2 points)

Grading rubric:

• Documentation (9 points)
• Solution complete and working properly (16 points)
