Question

You’ve been given a list of books to read over the summer, but you only want to read the books by a certain author.

Write a method

public List<Book> filterBooks(List<Book> readingList, String author)

That takes a List of Books as a parameter, removes all Books from the readingList that are not written by the given author, then returns the resulting list.

You can access the author of a Book by calling book.getAuthor(). The Book class is provided for reference.

public List<Book> filterBooks(List<Book> readingList, String author)
{
// Remove all Books from the readingList that are not
// written by the given author. Return the resulting List

for(int i = 0; i < readingList.size(); i++)
{
//does current author == author?
String currentBook = readingList.get(i);
if(!currentBook.getAuthor().equals(author))
{
readingList.remove(i);
i--;
}
}
return readingList;
}

Book.java

public class Book
{
private String title;
private String author;

public Book(String theTitle, String theAuthor)
{
title = theTitle;
author = theAuthor;
}

public String getTitle()
{
return title;
}

public String getAuthor()
{
return author;
}

public String toString()
{
return title + " by " + author;
}

public boolean equals(Book other)
{
return title.equals(other.title) && author.equals(other.author);
}
}
