weird foreach

gistfile1.java

Set<Author> authorsSet = new HashSet<Author>();
try {
    for(int i=0; ; i++) {
        // checking if author already exists in the DB
        Author author = authorDAO.findAuthorByName(authors[i]);
        if (author == null) {
	    author = new Author();
            author.setName(authors[i]);
        }
        
        authorsSet.add(author);
    }
} catch(ArrayIndexOutOfBoundsException e) {
    // ignore; this just means that i has reached the end of the array
}
