(The types do not need to be related in any particular way. This is because a dynamic value of null can convert to any reference type.) If T0 and T1 are primitives, then a Java method invocation conversion (JLS 5.3) is applied, if one exists. (Specifically, T0 must convert ...

You can form constructor references with array types. For example, int[]::new is a constructor reference with one parameter: the length of the array. It is equivalent to the lambda expression n -> new int[n].Array constructor references are useful to overcome a limitation of Java: It is...
