, all non-static constructors are also referred to as instance constructors.　2. Static ClassWe often want the class to contain only static members, and cannot be used to instantiate objects such as the console. A simple way to do this is to use a static class instead of setting the class's constructor to private. A static class can contain only static members and does not require an instance constructor because, by definition, it cannot be instantiated at all. However, a static class can have a

The public interfaces of classes represent everything that external users should know or can know. private method data can only be accessed through the member code of this class. this ensures that no unexpected events will occur.4.
