Pls help me with this program - urgent

Question

Hi,
I am new to Java. First time to do the program. Stuck here.
The description of the program:
Implement a complex number (numbers of the form a+ib, where i2 = -1, i2 is i raised to power 2 ). Recall that a complex number consists of a real part (a) and an imaginary part (b). Provide a reasonable set of constructors; the methods add, subtract, multiply and divide; as well as toString and equals.
You are to implement a complex number as having two fields, one for the real part another for the imaginary part.
If z = a + ib and x = c + id are two complex numbers, then their sum z+ x = (a+c) + i(b+d), quotient z/x = (ac+bd)/(c*c+d*d) + i(-ab+bc)/(c*c + d*d). two complex numbers are equal if their real and imaginary parts are equal.
I really do not have any clues about imaginary parts and how to do it.
Could you please help me with that.
Thanks a lot.

Answer 1

ur dboubt has nothing to do java.. its a mathematical concept..
as the question says the complexnumbers can be represented in the form of a+ib where i=squre-root of -1 .. and as this is imaginary (ie u cant get a minus number by squring a number) the second part is called imaginay.
so as a programmer u dont have to give more strain on this but to declare a class having to instance varaiables and inplememts the methods as said.
and in the toString() method u can return the numbers in the reuired format like
return ( a + "+i" +b);
