Arithmetic 2 's Design Thinking Chapter New requirements for the four Operation program:1. Avoid duplication of topics;2, can be customized (quantity / printing method);3, you can control the parameters:Whether there is a multiplication method, a range of values, plus or minus a negative number, division has a zero, whether the support score (true score, false score,... ) )Request One,First, solve the fir

only use a table, and precisely facade class also according to the table, then the number of calls to the facade class will inevitably increase. 3. Application Advantages of abstract Factory + reflection + configuration fileWhen it comes to the factory family, it's hard to think of their fondness for switch statements, but if the number of database tables is too large and requires different database switching, Swtich will inevitably add a lot of meaningless judgments, so that through the Factor

Legend has it that object-oriented development patterns were first created by lazy programmers. Development so far, people from the initial hot loyalty to discuss whether a certain language is enough object-oriented to now start a broader focus on object-oriented thinking rather than concrete content. Object-oriented thinking is actually not abstruse, it exists only for one purpose: Let the program developm

Through the previous three lessons, we have mastered the method of making animation, although the animation is still very simple.
