Answer 12

termLab.add(termLab, console);

you definitely can't do that. just what the compiler is saying: you can add a container to itself. when the compiler errors, it will give you a line number. Go to the line number as a starting point to solve.

Answer 13

Oh wow. I totally missed that. that should read:

midPanel.add(termLab,console);

Answer 14

lol

Answer 15

it's almost always something silly like that :).

Answer 16

Well one thing I have learned is that it is usually the really simple things that get over looked.

I was have some trouble with my previous version and it was as simple as not adding a button to my listener. That too took a second pair of eyes to point out.

Answer 17

heh yea always happens. if you find yourself looking the same problem for over 30 minutes, it can often be good to take a break, even for another 30 minutes. then you get a fresh look at it.

Answer 18

Answer 19

Yeah I do that . . . sometimes. I often find myself spending too long on something because I think I can figure it out in a few more minutes . . . and a few more minutes . . . and a few more minutes . . .

Answer 20

I will mos def get you a medal. the program works now. It just has some major formatting issues that shouldn't be too hard to fix (I hope).

Answer 21

eclipse will not alert you to this type of error because it occurs at run-time
