Given a HashSet<String> with elements {"apple", "banana", "cherry"}, what will be the result of adding a new String object with value "banana"?
Multiple choiceHardchapter-4-curatedpremiumcollectionsset-interface-and-hashset
Answer and explanation
Correct answer
D. The size remains the same, and "banana" is not added
Why
Since HashSet does not allow duplicates, adding another "banana" will not change the set, and its size will remain the same. The existing "banana" remains unaffected.
