() method is often in a class that has no other methods, by convention. It can be in any class, though some choices would see
ells Java where to start the program; it s just a naming convention
asily have been called startHere()
examples we have only one class, so it will seem there s a main() method in each class. Not so.
at a later point in the term will be minimalist:
es the least possible work to get the program running and then hands off all the remaining work to objects and their methods.
since we haven t covered classes and objects, we ll do everything in main() for a little while longer.
