1z0-829 Exam - Question 14

Question

Given:What is the result?

Examice · Accepted Answer

The provided code uses Java Streams to count the occurrences of each string in the list 'elements'. The code groups the list by each unique string and counts the number of times each string appears. Therefore, the result will be a map where keys are the unique strings and values are the counts of those strings. Given that the list contains three 'car', two 'truck', one 'bicycle', and one 'motorcycle', the correct output will be {bicycle=1, car=3, motorcycle=1, truck=2}.
