Assignment 02 – Rosie’s Road Co.
You must work in alone on this assignment. Do not use any Java language features we have not cover so far in this course.
Assignment Objectives
After completing this assignment the student should be able to:
● Write, compile, and run a Java program
● Use System.out to display prompts and other information to the user
● Collect input using a Scanner object
● Declare and use variables
● Use math operators and expressions to compute desired values
Assignment Requirements
For this assignment you are given the following files:
Assignment02.java (you must complete this file)
Problem Description and Given Info
Within the main method in the Assignment02.java file, you must write a program to compute the materials and costs
required for a specified road construction project.
Your program must prompt the user to enter the 4 input values described below. It must collect the user’s input and
store these values in 4 different variables. It must collect the inputs in the order shown below.
Inputs
1. Length of road project (miles) – data type double
2. Number of lanes – data type int
3. Depth of asphalt (inches) – data type int
4. Days to complete project – data type int
Outputs
1. Truckloads of Asphalt – rounded up
2. Stoplights
3. Conduit Pipes – rounded up
4. Crew members – rounded up
5. Cost of Asphalt
6. Cost of Stoplights
7. Cost of Conduit Pipes
8. Cost of Labor
9. Total Cost
Other Details
Rosie's Road Co. is a new construction company. They are interested in bidding on new highway construction projects
around the city. They've hired you to develop a software tool that they will use to help determine material needs and
costs.
Road development is not only the asphalt you see - water and power conduits must be installed at the same time, and
we have to account for things like labor costs and how long it will take to complete a particular project.
The city is very regular grid, with one 4-way intersection at each mile of road. When asking for a quote, the city sends
out the number of linear miles of road, and how many total lanes (1 to 8).
Here's some information that you might find useful as you complete this challenge.

1. The trucks hauling asphalt have a maximum capacity of 5 US tons (10,000 lbs)
2. The standard road lane is 12 feet wide.
3. Asphalt weighs 150 lbs per cubic foot
4. Asphalt costs $200 per ton
5. Power and water utilities are run in a conduit pipe under the road as part of all road projects
6. Conduit pipe is available only in 24 ft. lengths - each length costs $500
7. There is one intersection for every mile of road
a. a 1 mile road has 1 intersection
b. a 2 mile road has 2 intersections
c. a 2.99 mile road has 2 intersections
8. Stoplights cost $25,000 per light
9. Each intersection has two stoplights, plus one additional stoplight for each lane
a. a 1 lane road has three stop lights at each intersection
b. a 2 lane road has four stop lights at each intersection
c. a 3 lane road has five stop lights at each intersection
10. Work days are 8-hour days
11. All workers are paid $25 per hour.
12. Crew members can complete an amount of work in a specified time according to the equation below:
𝑐𝑟𝑒𝑤𝑀𝑒𝑚𝑏𝑒𝑟 =
50 ∙ 𝑚𝑖𝑙𝑒𝑠 ∙ 𝑙𝑎𝑛𝑒𝑠
𝑑𝑎𝑦𝑠
