Initializing a Double and Integer values inside a private method returns Null in both.
But when I'm initializing them normally inside the constructor (without a private method) then everything works perfectly.
why?
(line 65)
Thank you!!

@Twala
Here is the thing I don't understand.
Because it's pass-by-value, then the values that suppose to pass into polynomCoeff and PolynomPower are the values of polynom._coefficients.get(index) and polynom._powers.get(index) respectively, since it passes by them value of it...
But it passes Null instead of a value, that means both
polynom._coefficients.get(index)
and
polynom._powers.get(index)
are null, why? it makes non-sense
The pass-by value here are:
polynom._coefficients.get(index) and polynom._powers.get(index) right?

I mean, constructors and methods aren't different. Here the variables have a conflicting scope because he declared parameters of the same name. It would be the same with a constructor.
That normally would have been responded with by that google search
Fundamentally, it just does't work to pass around parameters so that they're initialized. So trying to is useless. Instead, whatever you intend to do must be done another way
Here it would be easy to not pass the values you want as parameters, as passing null pointers is fundamentally useless, and instead just have the initiliazer method set the fields.
