Write a program that asks the user to enter a name and a gen

Write a program that asks the user to enter a name and a gender, and then reads the contents of the two files into two separate arrays, or ArrayLists. The program should search the arrays/ArrayLists for the name and then display a message indicating whether the name was among the most popular. The user should enter done as a name to exit the program.
