Hi bro, Thank you for the video on method reference. Kindly help me to understand Reference to an instance method of an arbitrary object of a particular type with below example. Example: String [] array = {"Code","Java","C++"}; Arrays.sort ( array, String:: compareToIgnoreCase); In this example ,String Class compareToIgnoreCase method having arguments then How ClassName:: instance method working here. Kindly help with this

@javatechie why didn't you answer this question please? I also found it pertinent.

If it takes a single argument of the type which you are getting from the stream then it will work

.min((Integer::compareTo)); but in this example compareto contains method parameter even though how can I access directly without creating object could you explain it

@@Javatechie Optional maximumNumber = numbers .stream() .filter(Objects::nonNull)// It filter non null elements .max((Integer::compareTo)); // returns maximum number and through exception if the element is null it filters non-null elements Optional minNumber = numbers .stream() .filter(Objects::nonNull)// It filter non null elements .min((Integer::compare)); 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);
