    Arrays.sort ( array, String:: compareToIgnoreCase);
    In this example ,String Class compareToIgnoreCase method having arguments then

      Compare is a static method we can Directly access by using class name but compareTo method is a non static method but how can we accessed by using class name but it contains also the method parameter you said that we can't able to access that method by using class name by method reference if the method contains method parameter

    Nice tutorial. Please share reason for map(ArrayList::new) in the following line you showed at the very end:
    It just prints empty ArrayList as many times as the number of employees. Not sure the intent of printing empty list. Thanks
    ______
    service.loadEmployeesFromDB().stream().map(Employee:getId).map(ArrayList::new).f
    orEach(System.out.println);
