Record macro and Repeat

I've been slowly updating my IntelliJ keybindings so that unbound keys are bound in ways that my hands expect from using emacs. It's been giving me a lot of "wow that makes me happy" moments from doing stupid things like splitting windows or closing the current editor without leaving the keyboard. But what I really need now is a command that will let me repeat the next command n times as in emacs C-x [n] [command] syntax. I'm probably missing something and am too lazy to research this just yet, but it seems likes it makes macros much less powerful if you can't record a macro that does something to one line and then have it executed an arbitrary number of times.
