Question

if we have super class people and there are 3 parameters in people constructor
then we are deriving a class student from people but we want 4 parameters in student and want to use base class 3 parameters and fourth one seperately
how I can implement
I have error incompatible type

Answer 1

"I have error incompatible type"

Post your code into Code Playground and post the link to us so we can see what you've tried. If nothing more, copy/paste the actual error.

Answer 2

Without reading your code maybe you want to pass the the four parameters in the People constructor and then the three parameters required for the superclass using the super () method which is a call to the constructor of your superclass and hopefully it may resolve then.
