Question 5: Add a method called save to your Person class. This method will write the object out to a binary file. Use the Serializable format. Name the file accountNumber.dat where accountNumber is the credit card number from the object. NOTE: I just need help displaying the information. When I run my code, all the information is messed up, and I do not know how to fix it. ================================================== Given file Demo for Question 5 ------------------------------------------- import java.io.*; import java.util.Scanner; public class Demo { public static void main(String[] args) throws IOException, ClassNotFoundException { Person test1 = new Person("Eachelle Balderstone", 30526110612015L, 9866.30, false); Person test2 = new Person("Brand Hallam", 3573877643495486L, 9985.21, false); Person test3 = new Person("Tiphanie Oland", 5100172198301454L, 9315.15, true); test1.save(); test2.save(); test3.save(); Scanner keyboard = new Scanner(System.in); System.out.println("Enter file name"); String filename = keyboard.nextLine(); FileInputStream istream = new FileInputStream(filename); ObjectInputStream ois = new ObjectInputStream(istream); Person p = (Person)ois.readObject(); ois.close(); System.out.println(p); } }

This code below is from question 3 (part of it is mine and it worked)

//Look at my code at the end
