You need to create the array first, then initialise its elements:

code:

IntTuple[] changeArray = new IntTuple[arraySize];
for (int i = 0; i < arraySize; ++i)
    changeArray[i] = new IntTuple(arrayRows);

January is month zero, so you'll need to subtract one from the months before setting the calendar.

You can also make ProfitModel.stepTwo abstract:

code:

public abstract class ProfitModel {
    protected void stepOne() { ... }
    protected abstract void stepTwo();
    protected void stepThree() { ... }
}
//...

Doing this means that ProfitModel can't be directly instantiated, only its subclasses, which might be what you want.

e: ^ also make the inner methods protected

If you have a public (non-inner) class called Something in package wherever.blah, it has to go into $CLASSPATH/wherever/blah/Something.java. The book probably should've mentioned this, but in future exercises when they have classes like this they mean them to go into separate files.

Also, you're missing two }s at the end of the first class.
