if anyone knows java please hit me up on xifre. i could really use some help with this homework assignment

here is the assignment...

 

About the Application File

• 
  The Complex objects should be
  created in the application file and call the class methods.

• The
  application program should contain a while loop that stops processing when all
  of the data from one file has been read.

• If
  the file is empty, then a message should be displayed and all processing
  terminated.

• No
  calculations should be performed if the second set of values is zero for both
  the real and imaginary parts.  An error
  message should be displayed and processing should continue with the next set of
  numbers.

• 
  The application program should contain one method that prints, but does
  not call the arithmetic methods, the labeled results of all arithmetic
  operations (Specifics for output on next page.)

• 
  The application program should have a heading that contains the
  following information: your name, COSC1437, Programming Assignment #1, and the
  current date

 

About the Class File  - use this
in your code

Create
a Complex number class that has two
double fields, one that represents the real part and one that represents the imaginary
part of a complex number.  All class
methods should use the this reference
when referring to the calling object.  You
should also have the following class methods:

• Three class
  constructors:  a default constructor with
  the real part assigned 1 and the imaginary part assigned 0 and another
  constructor that has two parameters that initialize the real part and the
  imaginary part of the complex number and a copy constructor.

• One set operation with two
  parameters that assigns values of the real part and the imaginary part of the
  complex number.

• Two get operations:  one that returns the real part and one that
  returns the imaginary part.

• Four arithmetic operations
  that will add, subtract, multiply, and divide two complex numbers.  These should be non-void (value-returning)
  methods that receive one Complex
  object and return one Complex object.  (Do not use a shallow copy.  The getData method on page 356-357 (5^th
  edition) and page 338-339 (4^th edition) gives you an example of how
  to return class objects.).

• A toString method that writes only
  the value of the Complex object in
  the form a + bi .

An equals method that will
compare two Complex objects.

this is what i got...

 

Application file....

 

 

import java.io.File;
import java.io.FileWriter;
import java.io.PrintWriter;
import java.util.Scanner;

import prog1.Complex;

public class Imaginary
{
    public static void main(String[] args)
    {
        String infile;
        String outfile;
        String str;
        Scanner inputFile;
        PrintWriter outputFile;
        Complex first;
        Complex second;
        
        Scanner keyboard = new Scanner(System.in);
        
        System.out.println("Enter input file name :");
        infile = keyboard.nextLine();
        File myFile = new File(infile);
        inputFile = new Scanner(myFile);
        
        if(!inputFile.hasNext())
            System.out.println("Nothing there!");
        
        System.out.println("Enter output file name :");
        outfile = keyboard.nextLine();
        outputFile = new PrintWriter(new FileWriter(outfile));
        
        while(inputFile.hasNext())
        {
                if(second.getReal() == 0 || second.getImaginary() == 0)
                    System.out.println("Can't use those number");
                else
                    
        }
