i dont know how to do this in java

For this programming assignment, download the following AQI data in CSV files.

$1.$ LA County Daily AQI Data for CO pollutant measured in $2023.$

$2.$ LA County Daily AQI Data for Pb pollutant measured in $2023.$

$3.$ LA County Daily AQI Data for NO$2$ pollutant measured in $2023.$

$4.$ LA County Daily AQI Data for Ozone pollutant measured in $2023.$

$5.$ LA County Daily AQI Data for PM$2\mathrm{.}5$ pollutant measured in $2023.$

$6.$ LA County Daily AQI Data for PM$2\mathrm{.}5$ pollutant measured in $2023.$

$7.$ LA County Daily AQI Data for SO$2$ pollutant measured in $2023.$

Read AQI data stored in CSV files. Understand the headers, identify possible values $($data type$)$ for each column, and interpret what each row of

$-$ How many data collection sites are in the LA county?

$-$ How do you think your city's air quality is calculated when there is no data collection site is in your city? Write your proposal.

Write a program to do:

$-$ Load A CSV file using OpenCSV library opencsv$-5\mathrm{.}8-1.$jar $\backslash (\backslash$downarrow $\backslash )$ commons$-$lang$3-3\mathrm{.}13\mathrm{.}0.$zip $\backslash (\backslash$downarrow $\backslash )$

$-$ Create an array list of String named dailyAQI and store each row into the array. First, scan the CSV file and determine the size of the array list.

$-$ Create a hash table named sites.

$-$ Use an int data type for key to store site id$.$

$-$ Use a string data type for value to store site name.

$-$ Create a hash table named aqsParameters.

$-$ Use an int data type for key to store AQS Parameter code.

$-$ Use a string data type for value to store AQS parameter name.

$-$ Display all the names of the unique data collection sites.

$-$ Accept a site name from the user and report the daily AQI values for each AQS parameters.
