String: Text (e.g. "water", "everything is awesome",
"seven", "7"). When you input a string, the value must be in
quotes.
int: Integer (e.g. 7, 16543).
double: A value with a decimal point, a fractional value
(e.g. 7, 7.0, 7.4, 1253.654). An integer value (7) CAN be
stored in a variable of type double, but a double value (7.2)
CANNOT be stored in a variable of type int.
Work on Outlab 1. You should be able to make all of the
instance variables and the constructor (Steps 1-4 in the
assignment). Manually instantiate GroceryItem objects using your
new class and the constructor you made. Note: The Driver will
not compile yet, but GroceryItem should. Just press the
"Compile" button in the upper left corner of the window where
you see the GroceryItem code.
