java is disregarding negatives at will?
here is my current code:
as you can see, subtract and multiply are not giving what they should output (i haven't fiddled with divide yet). i have no idea how it got to -2 as it supposed to be doing (-3-2) . i'm just not sure what's causing it to go wrong as my code seems perfectly logical. help?removing code for privacy purposes.

Re: java is disregarding negatives at will?
I have not yet analyzed your code in detail but ..... at conceptual level if you do for example:Originally Posted by taze
a.add(b)
The result should be provided in one of these two ways:
- updating the a object (eventually returning the this, which is a).
or
- returning a new object.
depending on if the objects of this class are "mutable" or "immutable". But normally not updating b which can lead to confusion!

Re: java is disregarding negatives at will?
Wrong output is because real and imaginary fields of oneValue and anotherValue are updated after add operation.
Thats obvious when you use oneValue.add(anotherValue) and use the same variables to set the data.
Rather you should have created a new Complex2() object inside those mathematical methods and return that value.
