Question
1. Copy the files Address.java (Code Listing 8.1), Person.java (Code Listing 8.2), Money.java (Code Listing 8.3), MoneyDemo.java (Code Listing 8.4), and CreditCardDemo.java (Code Listing 8.5) from the Student CD or as directed by your instructor. Address.java, Person.java, MoneyDemo.java, and CreditCardDemo.java are complete and will not need to be modified. We will start by modifying Money.java. 2. Overload the constructor. The constructor that you will write will be a copy constructor. It should use the parameter Money object to make a duplicate Money object, by copying the value of each instance variable from the parameter object to the instance variable of the new object Code Listing 8.3 (Money.java) /** This class represents nonnegative amounts of money. */ public class Money { // The number of dollars private long dollars; // The number of cents private long cents; /** Constructor @param amount The amount in decimal format. */ public Money(double amount) { if (amount < 0) { System.out.println("Error: Negative amounts " + "of money are not allowed."); System.exit(0); } else { long allCents = Math.round(amount * 100); dollars = allCents / 100; cents = allCents % 100; } } Copyright © 2016 Pearson Education, Inc., Hoboken NJ // ADD LINES FOR TASK #1 HERE // Document and write a copy constructor /** The add method @param otherAmount The amount of money to add. @return The sum of the calling Money object and the parameter Money object. */ public Money add(Money otherAmount) { Money sum = new Money(0); sum.cents = this.cents + otherAmount.cents; long carryDollars = sum.cents / 100; sum.cents = sum.cents % 100; sum.dollars = this.dollars + otherAmount.dollars + carryDollars; return sum; } /** The subtract method @param amount The amount of money to subtract. @return The difference between the calling Money object and the parameter Money object. */ public Money subtract (Money amount) { Money difference = new Money(0); if (this.cents < amount.cents) { this.dollars = this.dollars - 1; this.cents = this.cents + 100; }
Hi, I am stuck on this coding question....I am not sure how to start. I also posted the coding for the question. thank you in advance.
