java - Reusing Supplier, Function and Consumer objects -

currently using completablefuture port streamsupport library implement chain of asynchronous tasks perform io operations.

as function , supplier objects became bit large taste, wanted move them, resulting in code like

private function<boolean, boolean> getemptybufferfunction() {     return new function<boolean, boolean>() {         @override         public boolean apply(boolean didprecedingsucceed) {             /* body */         }     } }; 

while works, curious whether practice re-created each time method called, or if better practice have implementation final objects , re-use them. i.e.

private final function<boolean, boolean> emptybufferfunction = new function<boolean, boolean>() {         @override         public boolean apply(boolean didprecedingsucceed) {             /* body */         }     } };
