Question 145
and the code fragment:Correct Answer: B
The code first creates a list of Person objects with the specified names and salaries. It then creates a stream from the list and filters the stream to include only those Person objects whose first name starts with 'J'. This results in two Person objects: 'John' with a salary of 2000 and 'Joe' with a salary of 1000. The mapToInt(Person::getSalary) method converts the salaries into an IntStream with values 2000 and 1000. The average() method calculates the average of these salaries, which is 1500.0. Therefore, the correct result is 1500.0.
