Assume that a gallon of paint covers about 350 square feet of wall space. Finish PaintCalculator.java, which should:

Calculate the wall area for a room

Calculate and return the number of gallons of paint needed

Display the number of gallons needed

Compute the price based on a paint price of $32 per gallon, assuming that the painter can buy any fraction of a gallon of paint at a fraction of the price of a whole gallon

The main method displays the final price. For example, the cost to paint a 15-by-20-foot room with 10-foot ceilings is $64.
