Java files not compiling

Question

i have 3 java files that im trying to compile for my CS class:
IntCalc.java
IntCalcPanel.java
IntCalcGUI.java
the panel uses IntCalc for an object and the GUI uses the panel as an object.
i cannot compile the panel or the GUI in the command prompt because it says
IntegerCalculatorPanel.java:17: cannot find symbol
symbol : class IntegerCalculator
location: class IntegerCalculatorPanel
IntegerCalculator calc = new IntegerCalculator();
^
IntegerCalculatorPanel.java:17: cannot find symbol
symbol : class IntegerCalculator
location: class IntegerCalculatorPanel
IntegerCalculator calc = new IntegerCalculator();
^
2 errors
even though all three files are in the same directory
these files WILL compile if i use an IDE. i tried jGRASP and they compile and run fine.
what do i do to fix this?

For classpath, you can shorten the word to "-cp", I
believe (it doesn't work on our Java at work, becauseNo, that will not work in this case!
-cp only works on the java command (to execute Java programs), not on javac (the compiler). Stupid, isn't it?
Make sure that your CLASSPATH environment variable is not set - that will make Java use the current directory as the default, and you won't have to type "-classpath ." every time.
If you're starting a serious project with lots of source files, I suggest you have a look at Ant to manage your build process.
