What is wrong with the following code? How can you fix it?

I want to remove the book that is sent to the function removeAllBooks

// Remove all the books which contain the given keyword in book title
    public void removeAllBooks(String keyword) {

        for(Book b: booksList) {
            if (b.getTitle().indexOf(keyword)>=0) {
                booksList.remove(b);
            }
        }
    }

Use `booksList.removeIf(b => b.getTitle().indexOf(keyword)>=0);`. – Johannes Kuhn May 21 '22 at 22:57
`// Remove all the books which contain the given keyword in book title public void removeAllBooks(String keyword) { for(Book b: booksList) { booksList.removeIf(b => b.getTitle().indexOf(keyword)>=0); } }` Do it like this ? – Omar May 21 '22 at 23:00
No, just the single line `booksList.removeIf(b => b.getTitle().indexOf(keyword)>=0);` inside the method. – Johannes Kuhn May 21 '22 at 23:03
It's `->`, not `=>`. – Louis Wasserman May 22 '22 at 00:36
