FRQ Question – Changing gears a little from arrays and arraylists, the other question will ask you to write an entire class.

The instance variables, the real constructor, (if you write a defauly constructor also no harm), accessors and methods requested.

On the next page you are to write the entire class!!!

public class ComplexNumber

{

//instance variables

//constructor

//accessor 1

// accessor 2

//add method

public ComplexNumber add(ComplexNumber cNum)

//multiply method

public ComplexNumber multiply(ComplexNumber cNum)

}
