can have only one direct parent (of course, the indirect parent class is random).Java inheritance is implemented by keyword extends, which inherits the parent class and can get all the methods and file of the parent class, but cannot get the constructor of the parent class.Here is a description of where inheritance needs attention from several directions.1. Overriding methods of the parent classIf a method of the parent class is visible to the child class (not private), and then a method is def

1. Background map fill This is one of the most widely used practices, no hacks, recommended use: Head Sideleft Default length Extended page It is not easy to move from a fixed, pixel-based design approach to a resilient, relative design approach. But if used properly, it can be a natural selection to enhance affinity and ease of use without sacrificing design. Pixels are non-scalable points on the computer screen, and aH3 is a word-sized block. Due

The tutorial introduces the most basic method of image synthesis. Before the synthesis need to find similar material, adjust the ratio, the original material parts do not need to use a stamp and other tools to erase, in exchange for the desired material. Later, the whole can be polished. Final effect 1, first open ostrich material. 2. Copy a layer and use the Stamp tool to sample the grass and soil nearby and smear the

tears in his career setbacks, and Mr. Liu Chuanzhi once told Mr. Yang Yuanqing that when you are as big as an ostrich, the chicks will be convinced. Only by winning this kind of "server" can we meet the core requirements of the same generation. The implication here is that two cocks may have a long tail and a bright crown, but at this time people often cannot tell which one is better. If your tail is long, you may complain about the bright crown. If

principle. Liskov substitution principle (LSP)-Rishi replacement principle Software Engineering guru Robert C. Martin finally simplified the Li's replacement principle into one sentence: "subtypes must be substitutable for their base types ". That is, subclasses must be able to replace them with their base classes. That is, the subclass should be able to replace any location where the base class can appear, and after replacement, the code will work normally. In addition, conditions such as if/e

commitment on the wine table, but did not expect this to be an embarrassing situation. Think about it carefully. This embarrassing situation is inevitable. From the very beginning, it is doomed that the boss will clap the table on this day. As a result, many project managers are accustomed to adopting the ostrich tactics, that is, to conceal problems and difficulties, so that problems and difficulties are accumulated day after day and become bigger a

with problems when you meet them:Suppose, we have a base class of "birds" (Tbird), there is a universal method of "Fly" in the class. And for this class derived some subclass "seagull" (tgull) and so on, these seem to be quite normal, but when we define "ostrich" (Tostrich), found that the ostrich is not actually fly, but he ran quickly, then someone will simply cover the base class (Fly) method, Do not gi
