Please help with correcting calling class and method errors

Question

Hi All,
I have created a game (like battleship) for 2 tanks. I can't seem to connect the classes and methods to get the values for the last die face rolled; last direction rolled on a 4 headed dice; the x and y position for each tank; the armour value and the firePower (or hit value) to print.
Each row of these values is supposed to print 50 times using a while loop.
(N.B. The code is appended below my name.)
Could anyone please help me? I would be most grateful. Thank you.
Steve

I got this sorted!
I unzipped the JAR and loaded the classes individually - so now the "reference" issue went away. Instead I now have a new problem, but I will post that seperately.
