You should create an istance of the object Profile like this:

  List<PointGrade> list = new ArrayList<PointGrade>();
  Profile profile =new Profile(list);

And you can use this istance maybe like this:

     profile.someMethod();

Create an instance of List:

List<PointGrade> list = new ArrayList<PointGrade>();

Populate it with some data (if you don't want to pass empty list):

PointGrade pg = new PointGrade();

//fill PointGrade fields you need

list.add(pg);

And then pass it to a constructor:

Profile profile = new Profile(list);
