I'm having trouble with this code. I'm sure it's something stupid (I'm in a class for Java) so please forgive this Java Newbie.

public class DataManagerBean implements DataManager {
ArrayList<Student> students = new ArrayList<Student>();

Student myStudent = new Student();
compileStudentInfo(myStudent);

while (cont) {
// Create the myStudent object and add data to it.

myStudent.setName(name);

}The problem is in the main method, where I'm trying to call the method compileStudentInfo which gathers a students information, creates a student object and then passes the object to the addStudent method which grabs the SSN of the student and calls the addGrade method. The addGrade method then creates an arraylist of courses for the student and returns that arraylist back to the addStudent method which adds the students courses arraylist to the students object and adds that student then to an arraylist of student objects. I know it sounds obscenely complicated and it is but it's the assignment that I have to do. (I'm sure it has to do more with us demonstrating concepts than anything else but I don't have a choice...I could have done this so much better with a mySQL database. LOL)
Anyways on the line in the main method that reads...
compileStudentInfo(myStudent);... I am getting an error that reads "non-static method compileStudentInfo(Entity.Student) cannot be referenced from a static context."
How can I fix this. I mean I need to be able to call a method that prompts the user for the information and creates the object. I am stuck with the method headers provided by the instructor. ANY advice would be greatly appreciated.
The student object is specified with this code if that helps.
