return an ArrayList method
- by Bopeng Liu
This is a drive method for two other classes. which i posted here
http://codereview.stackexchange.com/questions/33148/book-program-with-arraylist
I need some help for the
private static ArrayList getAuthors(String authors) method. I am kind a beginner. so please help me finish this drive method. or give me some directions.
Instruction
some of the elements of the allAuthors array contain asterisks “*” between two authors names. The getAuthors method uses this asterisk as a delimiter between names to store them separately in the returned ArrayList of Strings.
import java.util.ArrayList;
public class LibraryDrive {
public static void main(String[] args) {
String[] titles = { "The Hobbit", "Acer Dumpling", "A Christmas Carol",
"Marley and Me", "Building Java Programs",
"Java, How to Program" };
String[] allAuthors = { "Tolkien, J.R.", "Doofus, Robert",
"Dickens, Charles", "Remember, SomeoneIdont",
"Reges, Stuart*Stepp, Marty", "Deitel, Paul*Deitel, Harvery" };
ArrayList<String> authors = new ArrayList<String>();
ArrayList<Book> books = new ArrayList<Book>();
for (int i = 0; i < titles.length; i++) {
authors = getAuthors(allAuthors[i]);
Book b = new Book(titles[i], authors);
books.add(b);
authors.remove(0);
}
Library lib = new Library(books);
System.out.println(lib);
lib.sort();
System.out.println(lib);
}
private static ArrayList<String> getAuthors(String authors) {
ArrayList books = new ArrayList<String>();
// need help here.
return books;
}
}
