1. First, you will select a method that appropriately handles all of the included test cases by consulting the official Java documentation for the
Math class. Use the following tips to help you navigate the documentation:
• Scroll to the Method Summary section of the Math class and review the methods and their descriptions. Look for a method that will help
you round a value up to the nearest integer.
o If a method looks promising, click on its name to see a more detailed description. Pay special attention to the argument(s) and the data
type of the return value.
• Based on your review, select one or more methods from the Math class to use in your program.
2. Open the Virtual Lab by clicking on the link in the Virtual Lab Access module. Then open your IDE and upload the Paint2.zip folder. Review
the code for the Paint2.java class, looking for the comment //Complete this code block. Here, you will implement your selected method
so that your program meets the required functionality. The program should do the following:
• Calculate the number of paint cans needed to paint the wall.
• Round up to the nearest integer. Use the test cases to check your work.
Output the number of cans needed for the user.
