Any java boffins about that can check this for me. It keeps returning Grade as a null instead of the Character its ment to be set at. I need a fresh pair of eyes as I must be looking to hard at it now. Any help would be much appreciated.

//******************Allocate Grade***************************************

//declare Variables
Character grade;
if (Mark >= gradeLevels[0])
grade = new Character('A');
else if (Mark >= gradeLevels[1])

Also noticed: tempMark in updateStudentMark tempString in writeGradesToFile
are unused.
Hope that helps.
Cheers, Doesn't appear to work that way either. Thanks very much for looking at it though. I'll just do all the paper work for it and say it doesn't work then do it the Way I would have done it as a fix that should sort stuff out. (my way means new class array for Grades instead of adding it to the student_grades class.
