Question

*12.1 (Name for both genders) Write a program that prompts the user to enter one of the filenames described in Exercise 12.31 and displays the names that are used for both genders in the file. Here is a sample run:

Enter a file name for baby name ranking: Babynamesranking2001.txt
69 names used for both genders
They are Tyler Ryan Christian ...

The original question had me enter a URL and file to access all the data, but the website no longer contains the files we are told to use.
I am not sure how to show the files in this post, but they are listed as:
babynamesranking2001.txt
babynamesranking2002.txt
babynamesranking2003.txt
babynamesranking2004.txt

I guess if someone could just show me how to access and print the required data values from a file as described above then I could figure it out for these files.

This is originally a C++ programming question, but we are doing it in Java. I was hoping someone would know how to do it.

Answer 1

Note: Could you plz go this code and let me know if u need any changes in this.Thank You
