Which most closely matches a description of a Java Map?

  1. A vector of arrays for a 2D geographic representation

  2. A class for containing unique array elements

  3. A class for containing unique vector elements

  4. An interface that ensures that implementing classes cannot contain duplicate keys


Correct Option: D

AI Explanation

To answer this question, you need to understand the concept of a Java Map.

Option A) A vector of arrays for a 2D geographic representation - This option is incorrect because a Java Map is not specifically designed for representing 2D geographic data.

Option B) A class for containing unique array elements - This option is incorrect because a Java Map is not specifically designed for containing array elements.

Option C) A class for containing unique vector elements - This option is incorrect because a Java Map is not specifically designed for containing vector elements.

Option D) An interface that ensures that implementing classes cannot contain duplicate keys - This option is correct because a Java Map is an interface that ensures that implementing classes cannot contain duplicate keys. In other words, a Java Map is a data structure that stores key-value pairs and guarantees that each key is unique.

The correct answer is Option D.
