Why java has no not function/ alternatives for same [closed]

Question

Ok so if you want to check if a list is not empty

we would need to do something like

if(! mylist.isEmpty())

this affects code readability, so how can we write the same thing in a readable way, calling out negation of condition check.

One of possibility is to have a static helper function like:

static boolean not(boolean condition) { return !condition;}

How bad is this idea? Are there other options in apache common or guava etc? Or any other way you have achieved this?

Answer 1

It is not a bad idea in itself and it will not affect anything. However I think many people will disagree with you regarding the "unreadability" of the normal way of negating things using !.

if ( ! list.isEmpty() )

versus

if ( not( list.isEmpty() ) )

does not make much of a difference IMHO.
