Question

What is the return value of isEmpty() method of a map ADT when map has only 1 (key, value)

pair?

(a) 1
(b) true
(c) false
(d) null
(e) none of the above

Answer 1

The isEmpty() method returns false for a map with one (key, value) pair, as the map is not empty.

Step-by-step explanation:

The isEmpty() method of a map Abstract Data Type (ADT) is used to determine whether a map contains no key-value pairs. If the map contains no pairs, it is considered empty and the method will return true. Conversely, if the map contains one or more key-value pairs, the method will return false. Since the map in question has one (key, value) pair, it is not empty, and therefore the isEmpty() method would return false.
