Exercise 26: Writing an Application that Finds a User by Email

In this exercise, you'll write an application that reads the users from a specified CSV file into a hashtable, using their email as a key. They then receive an email address from the command line and search for it in the hashtable, printing its information or a friendly message if this isn't found:

In your UsersLoader.java file, add a new method that will load users into a hashtable using the email as a key. Create a Hashtable at the beginning and return it at the end:public static Hashtable loadUsersInHashtableByEmail(String pathToFile)

throws IOException {

Hashtable users = new Hashtable();

return users;

}
