IntelliJ IDEA: is there a way to format java code in a canonical way?












1















I have two java source files. Both represent the same class (semantically), but they were formatted differently.



For example, one of them contains the following line:



return Boolean.valueOf(Boolean.getBoolean("abc"));


While in the second file it looks like 2 lines:



return Boolean.valueOf(

        Boolean.getBoolean("abc"));


In both cases, when I apply formatting (Ctrl+Alt+L), these lines do not change.



Is it possible to format them in some canonical way: that is, to get the same code if the only difference is formatting?



Equivalently: is there any way to remove all ignorable whitespace? Such a 'dried-out' program would then be easily restored using 'Reformat code'.

          You should be able to do this if you turn off "Wrapping and Braces | Keep when reformatting | Line Breaks" in the Java code style settings.

          • Thank you both. I also had to put zeros in all 3 'Keep maximum blank lines' fields on 'Blank lines' tab to 'canonicalize' blank lines usage.

This is working fine when I in the field "when running a task, use the following user account:" insert BUILTIN User Group (for example: Administrators or Users). But when I try it with the created Local User Group (example: TestGroup) it is not working. The Users in the TestGroup are the same as in the Administrators group. What could be the problem?
