Using Inner join and sorting records in descending order

I am working with two tables(student_class and class) in my database. I have a query below that shows class that have students. But it is not quite what I am looking for. How to display classes that have students but show the results so maximum seats is descending. Would count be needed?

SELECT 
    class.class_name 
FROM 
    class 
INNER JOIN 
    student_class ON class.class_id = student_class.class_id; 

Tables:

Student_class:

         2         11

Answer

Just use an order by statement:

SELECT class.class_name FROM class INNER JOIN student_class ON class.class_id = student_class.class_id
ORDER BY class.max_seats_available DESC
