Can someone please explain to me why the constructor of the B and C class is calling Super(name) ?I am confused again. I am not modifying the parent class if I instantiate a new B or C class ? C c = new C ("Peter"); (Why would I want to pass that name to the Parent or Base (super) class ? What on earth is achieved by doing that ?) Thanks for your attention ;)

When I use "o." it gives oblect not found though its passed as part of parameter.

Question about the task Boss, something weird is happening
Java Syntax, Level 5, Lesson 12
Under discussion
Why I don't fill the requirements ? Using the "sz" parameter of "InputStreamReader"-It does read the numbers from the keyboard -There is only one main method (this one is valid) -The program displays a string that starts with "Sum =" -And it ends with the sum of the entered numbers. Maybe I have done something wrong but I struggle to find what, my code seems to be valid.
