Answer:
CREATE FUNCTION exam_eligible_students
RETURN NUMBER AS
num_students NUMBER(15);
BEGIN
SELECT COUNT(STUDENT_ID)
INTO num_students
FROM STUDENT_ATTENDANCE
WHERE ELIGIBILITY_FOR_EXAMS = 'Y';
RETURN (num_students);
END;
Explanation:
exam_eligible_students is a made of name for the FUNCTION to be called.
num_students is a made up name for the RETURN to be called. The RETURN name is referenced in the INTO statement and as the name of the the return in the RETURN line in ().
Here's the best answer I can give you, but bear with me.
The second option is incorrect because a class method must have a class identifier not an object identifier. What makes myObject an object identifier is the fact that it was created as an instance of the class MyClass in the constructor in line 5 (MyClass myObject= new MyClass(12.4,20);
The answer here should be MyClass.method2(20); Methods must have a set of parentheses, even if it has nothing inside. The first answer has a class identifier but the SOME_VALUE acts much like the Integer.MAX_VALUE; code which stores a constant value and does not actually perform tasks like most methods.
In short, the answer should be the last one but I hope my explanation cleared some things up for you, even if it was a bit more concept heavy than the question probably intended.
