I would like to follow conventions including that not exceed 80 characters per line.

I downloaded the PDF explaining the naming class, variables, and speaking a bit of wrapping but it's still light.

It is stated: - break after a comma - break before an operator - prefer high level breaks to lower

But how to manage a simple case as this one :

File logDir = new File(PropertiesLoader.getProperty(SpecificConstant.AdminStorageProperty.LOG_FOLDER.getValue()));

I am tempted to wrap after the parenthesis of getProperty.

If we cut before an operator, must we do that for all the following operators? I often see this code:

String value = SpecificConstant
    .AdminStorageProperty
    .LOG_FOLDER
    .getValue();

What is the better way to wrap lines ?

Thank you.

我使用 IDE 的默认设置，因此它会在我签入或要求时自动格式化我的代码。我很少手动格式化代码。

我会写

 File logDir = new File(PropertiesLoader.getProperty(SpecificConstant.AdminStorageProperty.LOG_FOLDER.getValue()));

as（在我的 IDE 中使用引入变量重构）

 String logProp = SpecificConstant.AdminStorageProperty.LOG_FOLDER.getValue();
 File logDir = new File(PropertiesLoader.getProperty(logProp));

我在我的 IDE 中使用了比例字体，使 80 个字符的限制变得不那么有意义；）对我来说，它通常更像是 200 个字符的限制。

恕我直言，80 宽度有点过时了，因为当时分辨率低，屏幕最好用 80 读取。

我在 IDE 中使用 120 作为默认宽度，并将其格式化为完全可读的代码。

File logDir = new File(PropertiesLoader.getProperty(SpecificConstant.AdminStorageProperty.LOG_FOLDER.getValue()));
