Java programming question?

Question

Write a program that prints its own grading form. the program should output the name and number of the class, the name and number of the programming assignments, your name and student number, and labeled spaces for scores reflecting correctness, quality of style, late deduction, and overall score. You must declare variables (Strings, int...) and use concatenation.

Answer 1

can you use J#?
Cause then you could use reflection (in System.Reflection namespace) to do that easy.

That should work, but I never compiled it so idk what errors will happen. Sorry that stuff isn't indented, I wrote it in notepad and when i copied it the tabs got lost.
