Java权限修饰符 访问权限两种(内部类可以是private或protected)修饰成员:对于一个类,其成员能否被其他类访问,取决于该成员的权限修饰符。在Java中,类成员的访问修饰符有四个:public、默认(包...:public、default、protected、private修饰的成员都能被访问。 在同一个包下的子父类中:除了private不能被访问,其它的都...

Here is a nice table which compares access level provided by public, protected, private and default access modifier in Java. As I said, use a public modifier to define API and use a private modifier to hide implementation, but you can also make constants public e.g. class variable which ...
