Consumer<List<Integer>> methodRef = Collections::sort;

I am trying to write the code around this syntax.

public static void main(String[] args) {

Consumer<List<Integer>> methodRef = Collections::sort;

        List<Integer> al = new ArrayList<>();
        al.add(1);
        al.add(4);

       methodRef.accept(al);
       System.out.println(methodRef);
}

the output is :
methodreferences.MethodReferenceTest$$Lambda$14/0x0000000800c01200@119d7047

please help me get the correct output.

I expect to see the list of sorted values method reference way.

>Solution :

Collections#sort sorts its input list.
System.out.println(al); to output the (now sorted) list.
