}• Software Engineering is offered at degree level only and requires a minimum of 180 points.
• Computer Science is offered at degree level (minimum 150 points) and foundation degree level (minimum 100 points).
• Information Systems is offered at degree level (minimum 120 points) and foundation level (minimum 80 points).
• Multimedia Studies is offered at foundation level only (minimum 120 points).
A Java GUI application is required to offer advice to prospective students on the selection of courses. The input information should be passed to an auxiliary class with a getAdvice() method which returns some advice to the applicant.
The advice to be offered is to proceed to room 101, 102, 103 or 104 for further details on Software Engineering, Computer Science, Information Systems or Multimedia courses respectively, or a suitable error message if the particular course/level combination chosen is not offered, or if the number of points is insufficient.
There should be a way of entering the course required, the level, and the number of points obtained, and a button which displays the advice when clicked.
