Comparator
interface that don't fulfill its contract.
Some method references, like Integer::max
, can be mapped to the Comparator
interface.
However, using them as Comparator
is meaningless and the result might be unpredictable.
Example:
ArrayList<Integer> ints = foo();
ints.sort(Math::min);
After the quick-fix is applied:
ArrayList<Integer> ints = foo();
ints.sort(Comparator.reverseOrder());
