You might at first think that you could just cast the gallonspaintneeded variable from a double to an integer type. however, that would merely cut off the decimal portion of the value, resulting in an underestimate of the number of cans needed. you might also consider rounding the number, but that would not work for the sample output provided above since normal rounding rules would suggest 2.0 cans, an underestimate. so, the computational problem you are faced with is to calculate the number of cans and round up to the nearest whole number. in order to determine if that method for rounding up exists as part of one of java’s core classes, we need to consult the documentation. there might be a single method that we can use or we might have to use more than one method.
