Sheet4 Sheet3 Sheet2 Sheet1 A switch with less than 3 branches is inefficient, use a if statement instead. 一个少于3个分支的switch语句是低效率的，应使用if语句。 Swith are designed complex branches, and allow branches to share treatement. Using a switch for only 2 branches is ill advised, as switches are not as easy to understand as if. In this case, its most likely is a good idea to use a if statement instead, at least to increase code readability. Avoid really long classes. 避免多长的类。 ExcessiveMethodLength Avoid really long methods. 避免过长函数。 Violations of this rule usually indicate that the method is doing too much. Try to reduce the method size by creating helper methods and removing any copy/pasted code. ExcessiveParameterList Avoid really long parameter lists. 过长参数列可以表明应该创建一个新的对象来封装众多的参数。从根本上来说，尝试对参数进行集合。 Long parameter lists can indicate that a new object should be created to wrap the numerous parameters. Basically, try to group the parameters together. TooManyFields Too many fields 太多的类变量 有太多类变量的类应被重新设计为含有少量的类变量，可能通过嵌套对象对信息归类。 例如，一个类包含有城市/国家/邮编成员变量应以地址类变量类代替。 Classes that have too many fields could be redesigned to have fewer fields, possibly through some nested object grouping of some of the information. For example, a class with city/state/zip fields could instead have one Address field. TooManyMethods This class has too many methods,consider refacting it. 这个类包含了太多的方法，考虑重构它。 在构造函数中调用父类 CheckResultSet Always check the return of one of the navigation method(next,previous,first,last) of a ResultSet. 始终检查记录集中的导航方法的返回记录（下一条，上一条，第一条，最后一条） Always check the return of one of the navigation method (next,previous,first,last) of a ResultSet. Indeed, if the value return is false, the developer should deal with it ! 函数/方法{0}()的执行路径复杂度是{0} The NPath complexity of a method is the number of acyclic execution paths through that method. A threshold of 200 is generally considered the point where measures should be taken to reduce complexity. Assigning an Object to null is a code smell. Consider r
