Mastering Java: The Ultimate Quiz for 'Thinking in Java'

Maps in Java are a specialized type of Collection that store key-value pairs. While they do implement the Collection interface, they do so indirectly through another interface called Map, rather than directly. Therefore, they are not a type of Collection, but they do use Collection methods to store and manipulate their elements. Option A is incorrect because while maps are related to the Collection interface, they are not a type of Collection. Option B is not accurate because Maps do in fact use Collection interfaces. Option D is incorrect because it directly states that Maps extend Collection, which is not true.
