I think you are going to have to provide a more detailed question. What is it exactly you are trying to do?
Hi, I am able to pull up the faculty list in the ArrayList,
What's the faculty list? There's a variable called "faculty" but it's not declared or initialized in the method. Is it type List? Is the faculty list "facultyChoice"?
but how can I assign the choice (m) to the Course?
What's the Course? You have an object of type Courses and you are passing m, which is null, to it.
