abstract horse head

Ma Tau and text is a whole effect, but the process is relatively cumbersome. Therefore, the horse's head and text to write separate tutorials. Horse head part of the focus is hand-painted, text part of the stereo effect can be. This tutorial only describes the MA tau part of the production. Final effect Add text after the effect. Text Tutorial Follo

-abstract methods. There is no implementation method in the interface.5. The variable defined in the interface is the public static final type by default, and must be given its initial value, so the implementation class cannot be redefined or changed.6. Variables in abstract classes are friendly by default, whose values can be redefined in subclasses or re-assigned.7. The methods in the interface are public

Abstract classes are often used to characterize the abstract concepts we derive in the analysis and design of the problem domain, as an abstraction of a series of concrete concepts that look different, but are essentially the same, and we cannot instantiate them (not get a concrete one) so they are called abstractions. For example: We want to describe "fruit", it is an abstraction, it has quality, volume an
