.③ from the problem domain perspective: Abstract class embodies an inheritance relationship in the Java language, in order to make the inheritance relationship reasonable, there must be an "is a" relationship between the parent class and the derived class, that is, the parent class and the derived

In our daily web development and Web application development, we often need to effectively invoke the JavaScript processing date and time format related functions, in JavaScript already contains some of the most basic built-in processing methods. Of course, if you have the time, you can fully develop and write their own methods, but the effective use of others have developed a good class library is certainly a better way to deal with, there is no need
