Fine air particles can come from power plants, motor vehicles, airplanes, residential wood burning, forest fires, agricultural burning, volcanic eruptions, dust storms, etc. Particles smaller than 2.5 micrometers are able to bypass the nose and throat and penetrate deep into the lungs and some may even enter the circulatory system. Due to the many adverse effects fine particles can inflict on a large number of people, PM2.5 is one of the major pollutants closely monitored by health authorities around the world. You will most likely come across a dedicated column for PM2.5 alongside the Air Quality Index (AQI), Pollutants Standards Index (PSI) or the air quality standards adopted by your country. The data provided to you in this assignment was obtained from the Geoplatform screening tool. The assignment only uses the PM2.5 levels from the dataset. Write one function in AirParticles.java. findHighestLevel(double[] communities) finds and returns the largest value in the double array communities. Each array index contains the PM2.5 level for a community in the country. Note 1: the function returns a double value. Note 2: do not update the argument array communities. The main method is implemented for you to test your function using the input file PM2.5.txt. Execute the program that reads the input file, populates the array, and call the findHighestLevel function as follows: java AirParticles < SmallerPM2.5.txt java AirParticles < PM2.5.txt In this function you are practicing finding the largest value in the input array and returning a value from a function.

Question

Fine air particles can come from power plants, motor vehicles, airplanes, residential wood burning, forest fires, agricultural burning, volcanic eruptions, dust storms, etc. Particles smaller than 2.5 micrometers are able to bypass the nose and throat and penetrate deep into the lungs and some may even enter the circulatory system.

Due to the many adverse effects fine particles can inflict on a large number of people, PM2.5 is one of the major pollutants closely monitored by health authorities around the world. You will most likely come across a dedicated column for PM2.5 alongside the Air Quality Index (AQI), Pollutants Standards Index (PSI) or the air quality standards adopted by your country.

The data provided to you in this assignment was obtained from the Geoplatform screening tool. The assignment only uses the PM2.5 levels from the dataset.

Write one function in AirParticles.java.

- findHighestLevel(double[] communities) finds and returns the largest value in the double array communities. Each array index contains the PM2.5 level for a community in the country.

- Note 1: the function returns a double value.
- Note 2: do not update the argument array communities.

The main method is implemented for you to test your function using the input file PM2.5.txt. Execute the program that reads the input file, populates the array, and call the findHighestLevel function as follows:

java AirParticles < SmallerPM2.5.txt
java AirParticles < PM2.5.txt

In this function you are practicing finding the largest value in the input array and returning a value from a function.
