java - Ternary operator is not a statement -

i've following ternary expression:

((!f.exists()) ? (f.createnewfile() ? printfile() : throw new exception("error in creating file")) : printfile()); 

for one, or more, reason don't know idea ide me isn't statement. why?

this not valid, need return value

printfile() : throw new exception("error in creating file") 

try one

if(f.exists() || f.createnewfile()) {   printfile(); }else{   throw new exception("error in creating file"); }
