Question

Use the following file for this assignment.

It contains the names given to male and female babies in 2013, along with the counts for each name in the list.

Once you have downloaded the file, look at it in a text editor to help you figure out how you will parse it.

Use Map<String,Integer> and Set<String> objects to help you determine the following:

- How many unique female names were there?

- How many unique male names were there?

- How many names were given to both males and females ("unisex" names)?

- How many female babies have the same name you do?

- How many male babies have the same name you do?

Submit your answers to the above questions, along with your .java file(s).

For this assignment, a single Java file that includes a main method is acceptable.

Feel free to explore additional questions (e.g. most common male and female names, least common names, etc.).
