Test Writing: Nearest Whole

Created By: Chris Taylor
/ Version: 2023.6.0

Write a method nearestWhole that accepts a list of Doubles and returns a list of Integers where each Integer is the integer nearest in value to the original Double. You may assume that the list passed is not null and does not contain any null elements. Your solution must make use of a stream and at least one lambda expression.

  • [1.8, 1.1, 1.4] -> [2, 1, 1]
