> Suppose we had used switch-expression in Java application (JDK-12)
> e.g.,
> int a = switch (num)
> { case 1 ->1; default->2; }
> ;
> It will show the below error:
> switch expressions are a preview feature and are disabled by default.
> (use --enable-preview to enable switch expressions)
>
> NetBeans doesn't provide the fix.
> Currently manually need to add '--enable-preview" in build configuration file .
