【Java学习】-Inheritance syntax
作者:互联网
You can create a main() for each one of your classes; this technique of putting a main() in each class allows easy testing for each class.
Even if you have a lot of classes in a program, only the main() for the class invoked on the command line will be called. Even if a class has package access, a public main() is accessible.
So to allow for inheritance, as a general rule, make all fields private and all methods public.
