Do you mean that the formatter does not break long lines  Check Settings   Project Settings   Code Style   Wrapping   Update  in later versions of IntelliJ  the option is under Settings   Editor   Code Style  And select Wrap when typing reaches right margin

Enabling  Ensure right margin is not exceeded  doesn t work for me in Intellij IDEA 2018 2  I have found the workaround  we need to change every elements below from  Do not wrap  to  Wrap if long       After that  we can preview what kind of wrap type will be changed by looking into right panel  If we are satisfied  Click  OK  or  Apply  to apply the changes  Finally we need a mannual format by using  CTRL  ALT  L in Windows and Command  Shift  L in MacOS
