Today, we have collected 10 excellent free ebook sharing designers. E-books represent the digital publications that people have read and distinguish them from traditional publications that use paper as the carrier. e-books use computer technology to extract certain text, images, sounds, images, and other information. Electronic Books are easier to carry and read

Learning design patterns have been a long time, in fact, has been knocked over once, but the old feel that nothing has been learned, not enough understanding, and now take advantage of the reconfiguration of the computer room, and then again, it is not too late. In fact, after knocking on the computer room, look at the mode, in fact, it was difficult to understand, it is difficult to read the code a glance can be read, while a little feeling, early ha

readers to a page, and in contrast, you can create an organized hierarchy between different elements. Keep in mind an important rule: to achieve effective comparisons, contrast must be strong. Don't be afraid to shrink. ? How is it implemented? You can increase the contrast by font selection, line width, color, shape, size, space, and so on. !! The problem to avoiddon't hesitate. If you want to make comparisons, increase your strength. Do not compare a thick line with a thicker line. Do not com

I. Overview of the pattern The Strategy mode (strategy pattern) is similar in shape to the state mode, but somewhat different in intent. The intention is to make these algorithms interchangeable and provide a way to select the most appropriate algorithm.

of the strategy model You can add a new policy without changing the current structure Can dynamically change policies at run time The strategy model embodies two principles: Find out where the program may need to be changed, and separate it so that the rest of it will not be affected by it.

Objective Just worked overtime, eh, the company stipulated that usually overtime only 10 dollars of meal supplement, Saturday and Sunday overtime, only to give a series of leave, in the state-mandated holidays in accordance with 3 times times the wages issued.

There are a lot of people in the design pattern who are addicted to the design pattern, and every few lines of code you have to consider--is there a need for a pattern! Remember. Mode is a set of coding

Intent Define a family of algorithms, encapsulate each one, and make them interchangeable. Strategy lets the algorithm vary independently from the clients that use it. Capture the specified action in an interface, bury implementation details in derived classes. Problem One of the dominant strategies of object-oriented design is the "open-closed principle ". Figure demonstrates how this is routinely achie
