Explanation / Answer

public class Library {
private ArrayList<Book> allBook = new ArrayList<Book>();

public Library(ArrayList<Book> other) {
if (other == null) {
throw new NullPointerException("null pointer");
} else
this.allBook = other;
}
public Library() {
this.allBook = new ArrayList<Book>();
}
public boolean add(Book book) {
if (book != null && !book.equals("")) {
throw new IllegalArgumentException("Can't be empty");
}
allBook.add(book);
return true;
}

public ArrayList<Book> findTitles(String title) {
for(Book b: allBook) {
if(title.compareTo(b.getTitle())== 0) {
return allBook;
}
}
return null;
}
public void sort() {
Collections.sort(allBook);
}

public String toString() {
return Library.this.toString();
}
}
public class Book implements Comparable<Book> {
private String bookTitle;
private ArrayList<String> bookAuthor;
public Book(String title, ArrayList<String> authors) {
if(title == null && authors == null) {
throw new IllegalArgumentException("Can't be null");
}
if(title.isEmpty() && authors.isEmpty()) {
throw new IllegalArgumentException("Can't be empty");
}
bookTitle = title;
bookAuthor = authors;
}

public String getTitle() {
return bookTitle;
}
public ArrayList<String> getAuthors( ) {
return bookAuthor;
}

public String toString( ) {
return bookTitle + bookAuthor;
}
public int compareTo(Book other){
return bookTitle.compareTo(other.bookTitle);
}
public boolean equals(Object o) {
if(!(o instanceof Book)) {
return false;
}
Book b = (Book) o;
return b.bookTitle.equals(bookTitle)
&& b.bookAuthor.equals(bookAuthor);
}
}
