Biodiversity by County - Distribution of Animals, Plants and Natural Communities in the State of New York(data.gov). This dataset lists Endangered or Threatened animals and plants that have been seen in New York.
Details
The columns in the data are in order:
- County
- Category
- Taxonomic Group
- Taxonomic Subgroup
- Scientific Name
- Common Name
- Year Last Documented
- NY Listing Status
- Federal Listing Status
- State Conservation Rank
- Global Conservation Rank
- Distribution Status
The two you parts you will need for the methods you are tested on are:
-
Category
this will be either Plant or Animal -
NY Listing Status:
This states whether it is Endangered or Threatened
Required Methods To Implement (graded)
We will grade the following methods. Please note, that while there may be different ways to implement them, and you are free to even write helper methods (which we did ourselves) - we need the method names to match the following specification.
CSVReader
This file specifically is used to read the Comma Separated Value files using a Scanner Object. We also used it to help store the indices of the columns in constant variables for easy use in GenderStats.java.
public void initialize(String file)
This method will initialize a class level scanner object based on a File (new File(…)). The name of the file will be passed in. You can assume it is a correct name, but you should also try and catch the IOException that is required by calling new file. The following code can help you get started. You may also want to look at the Digital Humanities lab for an example.
Here is some example code that will help you.
try {
fileScanner = new Scanner(new File(file));
}catch (IOException io) {
io.printStackTrace();
}
public boolean hasNext()
Returns if the scanner has more lines to read if the scanner has been initialized. If the scanner hasn’t been initialized, it will return false. Looking at how scanner checks to see if more lines need to be read will help with this method.
public String[] getNext()
If the scanner has more lines to read, it reads the line and returns a String array of all the values in the line - broken up by the comma (‘,’) delimiter! This is essentially how CSV files are stored.
Stats.java
This file is the main driver file of your program. It will calculate the percentage of endangered and threatened plants and animals.
The final output will print out “% of animals and % of plants listed are Endangered. While % of animals and % of plants listed are Threatened.” each sentence on a separate line and with the percent’s filled in.
For example:
22.76% of animals and 42.63% of plants listed are Endangered.
While 40.13% of animals and 32.13% of plants listed are Threatened.
Suggestions / Insights
Before you start coding it is always good to plan your code out. Look at what each method is asking for and think about how you can accomplish it. (Think about how a percent is calculated.)
If you would like to expand upon the data there are many different things you could look for. Examples are:
- The total species Endangered and/or Threatened
- Number of species spotted by county
- You can sort them by most recent sighting to least recent or vice-versa
These are just examples feel free to come up with your own ideas of sorting/processing the data.
