I think the major problem is a Java issue. The "==" operator compares
using object identity -- i.e., it tells you if two Strings (or in
general two objects) occupy the same physical location in memory. To
compare the contents of two Strings (or again, of two Objects) you
should use the "equals()" method, which compares the contents of the
Strings for equivalence. So everywhere you've got a line like the
above, change it to
> if(slotType[i].equals("double"))
and you should see substantial changes in the behavior of your program.
