Complete the following code snippet that returns a stream of Student objects, representing students who have a grade point average (gpa) of at least 3.8.Assume that studentStream is a stream of Student objects and the getGpa method returns a double representing the student's gpa.
Stream<Student> highHonors = studentStream
________________________________;
A).map(getGpa() >= 3.8)
B).filter(getGpa() >= 3.8)
C).map(s -> s.getGpa() >= 3.8)
D).filter(s -> s.getGpa() >= 3.8)

Quizplus · Accepted Answer

We need to filter out the students who do not have a gpa of at least 3.8, so we need to use the filter() method. The lambda expression in filter() should check if a student's gpa is >=3.8, so option D is the correct choice. Option A is incorrect because map() is used to transform each element in a stream, not filter them. Option B is incorrect because getGpa() cannot be used in the way presented in filter(). Option C is incorrect because the lambda expression should check if the student's gpa is >=3.8, not return a boolean value.
