These are simplified examples that show how to use the If-Else statement effectively. Another popular conditional statement used in Java programs is the If-Else If statement. This allows your program to test for more than two choices in a single If-Else statement. In fact, an If-Else If s...
6. 警惕冗余初始化 Therefore, a java best practice is to be aware of the default initialization values of member variables and avoid initializing the variables explicitly. Java 最佳实践是了解成员变量的默认初始化值并避免显式初始化变量,Java语言很多变量存在默认值,在自己编写初始化的时候不建议使用Java的...
在if和else的条件判断处打印参数。 Developer should also log exception to track the issue 对于异常信息必须打印。 更为合理的做法是像下面这样: Definitely don’t log every if-else statement! 不要在if/else分支中打印,更为合理的建议是记录响应以及错误。 Don’t log every method entry and exit! 不要...
The typical case is when you declare a final variable without assigning value to it, and then you have an if statement giving different values in the “then” and the “else” branch. Needless to say that the variable has to be initialized before the lambda expression is created. A ...

Definitely don’t log every if-else statement! 不要在if/else分支中打印,更为合理的建议是记录响应以及错误。 Don’t log every method entry and exit! 不要在每个方法的入参和出参打印。当然这并不是铁律,比如三方接口调用就必须要在“入口”和“出口”中打印以便快速定位问题和甩锅。
