Reading in Objects

[Johnny Donovan]

Hi Guys,

So im a little confused.

Say i have 2 Objects - An author object and a book object. Now i have a created class which implements a class which contains all the methods needed to get information for the objects ex. getAuthorName, getAuthorDOB, getBookName, getBookReleaseDate.

Now the book object also contains an authour object .

How would i get all the books written by a specific author using this method?

findAllBooks(Author){
}

Sorry i am trying to learn Java in my spare time but i am very confused.

Thanks you

In pseudo-code:

public List<Book> getBooksByAuthor(Author anAuthor) {
List<Book> booksOfAuthor ...
loopAllBooks {
if the author of the book is the same as anAuthor
add to booksOfAuthor
}

return booksofAuthor;
}

Thank you so much for replying.

My only problem now is how do i get the Books object?

You would have to put all your book objects into a List<Book> or a Book[] array when you create them. Then they are available for you to go through and look for the author.

So i could say :

List <Book> booksOfAuthor = new List<Book>();
for(int i = 0; i < Author.getBooks().getSize() ; i++){
list.add(Author.getBooks(i));
}
