java - Returning an empty array -

-

question

this may silly question, there difference between foo() , bar()?

code

private static file[] foo() {     return collections.emptylist().toarray(new file[0]); } 
private static file[] bar() {     return new file[0]; }

i'm trying think of best way return empty array, rather null.

a different way return empty array use constant empty arrays of given type same.

private static final file[] no_files = {}; private static file[] bar(){     return no_files; }
