Thread: Code Complete?

Hello, I am currently doing an assignment where i was given 3 java codes that was similarly to my assignment. I changed those codes to fit my needs and i was wondering if anyone had any better ideas that i can do with my code.
We had to make a .txt file that bascially defined a game you put in .
We had to include price, manufacturer, quantity, discount price, discount quantity, then two other programs to read and pull up the .txt file.
So.... here is my code thus far , I am open to suggestions to include more things in this code to better define the game. Also, I was wondering why the .txt file when i create it it reads a bunch of weird characters for instance "¬í sr EmployeeÔ½ªÿŸˆ; D QOHD QOH2I idNumD priceD price2L namet Ljava/lang/String;L name2q ~
L name3q ~
xp@. @.
@N @K€ t Lawlst Lawlst
C" this was the file it made when i viewed it from notepad using Lawls as game name and manufacturer just for example. I thought it would just list the names, prices, quantities in the txt file. If someone could explain this to me that would be cool.

import java.io.*;
public class Employee implements Serializable
{
   int idNum;
   String name;
   String name2;
   String name3;
   double price;
   double price2;
   double QOH;
   double QOH2;
   public Employee(int num, String name, String name2, String name3, double price, double price2, double QOH, double QOH2)
   {
      idNum = num;
      this.name = name;
      this.name2 = name2;
      this.name3 = name3;
      this.price = price;
      this.price2 = price2;
      this.QOH = QOH;
      this.QOH2 = QOH2;
   }
   public void display()
   {
	   System.out.println("serial # " + idNum );
	   System.out.println(" Game name:" + name);
	   System.out.println(" Manufacturer/publisher: " + name2);
	   System.out.println(" Original price: " + price );
	   System.out.println(" Quantity: " + QOH );
	   System.out.println(" Discounted price: " + price2);
	   System.out.println( " Quantity: " + QOH2);
	   System.out.println(" Game rating: " + name3);
   }
}
