Description
Basic Requirements
Create a program that reads solar energy production data for the last week from a file, gets
input for the cost of the system, and outputs production, savings, days to recoup cost and
years to recoup the cost.
Don’t worry about being a solar engineer, just use the techniques covered in this chapter. No
prior knowledge is required for solar energy. Refer to pages 102-103 for how to read from a
file.
LiFiUnit3.java - Main Method
The program should read in a file called “energyProduced.txt”. The contents of the file are
at the bottom of the requirements. The file should be a normal text file with no
special formatting. The file should be in the same directory as the program.
- Use a named constant for the cost of electricity at .085.
- Read in all data from the file. (refer to pages 102-103)
- Get input from the file and store production values for each in doubles.
- Get input for “Total system cost” in dollars and stored as an integer. Get input
on the same line as prompt, see an example.
- Output the following items per the sample below:
- Total Energy Produced in one week.
- Total Savings for one week (total production times cost for electricity)
- Total Savings per day (the average)
- Days to recoup the system cost (truncated)
- Use typecasting to integer to get rounded value
- Years to recoup the system cost (truncated)
- Use typecasting to integer to get rounded value
- Ensure columns are aligned, use escape characters to align columns.
