Complex numbers

Question

how can you represent a complex number as a class

Answer 1

class Complex{
int Real,Imag;
Complex(){}
Complex(int Real1,int Imag1){
Real=Real1;
Imag=Imag1;
}
Complex AddComplex(Complex C1,Complex C2){
Complex CSum=new Complex();
CSum.Real=C1.Real+C2.Real;
CSum.Imag=C1.Imag+C2.Imag;
return CSum;
}
} 
class Complexmain{
public static void main(String[] a){
Complex C1=new Complex(4,8);
Complex C2=new Complex(5,7);
Complex C3=new Complex();
C3=C3.AddComplex(C1,C2);
System.out.println("SUM:" + C3.Real +"+i" + C3.Imag);
}
}
