Sort Account-class

Use class "Account" (Shown below) and implement Comparable interface and use it to sort accounts.

The Program should:

- Implement Comparable interface, and be sorted by ; Account balance or datecreated if balance is same.

- To test functionality you have to create a constructor who recieves a GregorianCalendar object to specify when this account was created.

- In the test-class you must create at least 4 accounts where two have the same balance, but different date created.

- Add all objects to an ArrayList and sort in rising order.(Highest balance first)

- Print all accounts in ArrayList, should implement toString.

Output example:

Account-class:

class Account { private java.util.ArrayList transactions = new java.util.ArrayList(); private static double annualInterestRate; private java.util.Date dateCreated; private double balance; private String name; private int id;

public Account() { this ("Undefined", -9999, 0); }

public Account(String name, int id, double balance) { dateCreated = new java.util.Date(); this.balance = balance; this.name = name; this.id = id; }

public java.util.ArrayList getTransactions() { return transactions; }

public static void setAnnualInterestRate(double annualInterestRate) { Account.annualInterestRate = annualInterestRate; }

public static double getAnnualInterestRate() { return annualInterestRate; }

public java.util.Date getDateCreated() { return dateCreated; }

public void setBalance(double balance) { this.balance = balance; }

public double getBalance() { return balance; }

public String getName() { return name; }

public void setId(int id) { this.id = id; }

public int getId() { return this.id; }

public double getMonthlyInterest() { return balance * (annualInterestRate / 1200); }

public void withdraw(double amount, String description) { balance -= amount; transactions.add(new Transaction('W', amount, balance, description)); }

public void deposit(double amount, String description) { balance += amount; transactions.add(new Transaction('D', amount, balance, description)); } }

Transaction-Class:

class Transaction { private double amount, balance; private String description; private java.util.Date date; private char type;

public Transaction(char type, double amount, double balance, String description) { date = new java.util.Date(); this.type = type; this.amount = amount; this.balance = balance; this.description = description; }

public String getDescription() { return description; }

public java.util.Date getDate() { return date; }

public double getBalance() { return balance; }

public double getAmount() { return amount; }

public char getType() { return type; }

@Override public String toString(){ return String.format("%tF %1$tT %-15.2s%-15s%-15s%s", getDate(), getType(), getAmount(), getBalance(), getDescription()); } }
