complex questions

1.        The following code represents complex numbers in java. There are some blanks in the code. Please fill in the blanks.

class Complex

{

                int iReal,iImaginary;

            // insert zero parameter constructor and initialize iReal,iImaginary to 0.

               

                

               

           //  insert one parameter constructor to initialize the iReal,iImaginary with the parameter

 

           //  insert two parameter constructor to initialize the iReal,iImaginary with the two parameters passed

            

             Complex addComplex(Complex C1,Complex C2) // function to add the complex numbers

                {

                                Complex CTemp=new Complex();

                                CTemp.iReal=C1.iReal+C2.iReal;

                                CTemp.iImaginary=C1.iImaginary+C2.iImaginary;

                                return CTemp;

                }

           Complex subComplex(Complex C1,Complex C2) // function to subtract the complex numbers

           {

 

          

    

          }

}

class Complexmain

{

                public static void main(String[] a)

                {

                                Complex C1, C2, C3;

                        // create C1 with one parameter constructor

                       // create C2 with two parameter constructor

                            // create C3 with Zero parameter constructor

 

                    

                                C3=C3.addComplex(C1,C2); //function call

                                //Display the results

                                System.out.println("---Sum---");

                                System.out.println("Real :" + C3.iReal);

                                System.out.println("Imaginary :" + C3.iImaginary);

                }

}
