For this problem you will write code to manage bibliographic citations. Author To start, implement the class Author.java: Author - lastName : String get - firstName : String get - middleInitial : String get + Author(String, String, String) + Author(String) + getCitation(): String + splitAuthors(String) : Author[] The class has two constructors: 1. The first takes three String's and uses them to set the 2. The second takes the author's full name, and needs to do a bit of string processing to separate the attributes. Examples of valid inputs to this constructor are: "Henry David Thoreau" "Henry D Thoreau" "H. D. Thoreau" "Henry Thoreau" In every case, the three names are separated by only spaces, you can use name.split(" ") to separate the names into an array of substrings. The middle initial may not be present at all, in which case that attribute should be set to the empty string, (""); otherwise, the initial should be set in should come in the format: "D." capitalized first letter followed by a period. The method getCitation() should return a string in the format "Thoreau, H. D.", i.e.: , .
