Nullpointer Memes

Ah, the classic "I technically did what you asked for" defense mechanism. The function claims to check if a book title is a duplicate, but it's actually doing the exact opposite of what its name suggests. It prints "Book not in bookshelf" when it finds a match and "Book in bookshelf" when it doesn't. And that's not even addressing the potential NullPointerException lurking in the shadows. The perfect representation of "it works on my machine" energy. Simplified? Yes. Fixed? Absolutely not. It's like putting a fresh coat of paint on a car with no engine and calling it "simplified transportation."
