Oiel expert en polymo.....aidez moi

Voici mon probleme, j'ai commencer mon code comme ceci mais apparament il me manque mon polymorphisme pour pouvoir completer mon travail. Je ne demande pas de le faire pour moi mais bien me diriger dans la bonne direction avec des explications simples


Voici mon code:

[code]
class AccountRob {
public static void main(String[] args) {
/**set account opening*/
Account account = new Account();
System.out.println("Initializing account... " + account.getBalance());
account.setID(1122);
System.out.println("Retrieving customer ID #... " + account.getID());
account.setAnnualInterestRate(4.5);
System.out.println("Retrieving annual interest rate... " + account.getAnnualInterestRate() + "%");
System.out.println("Calculating monthly interest rate... " + account.getMonthlyInterestRate() + "%");
account.setBalance(20000);
System.out.println("Retrieving customers initial account balance... $" + account.getBalance());
account.withdraw(3500);
System.out.println("Retrieving customers account balance post withdrawl... $" + account.getBalance());
account.deposit(3000);
System.out.println("Retrieving customers account balance post deposit... $" + account.getBalance());

/**Print statement to customer*/
System.out.println("\n\nCustomer ID #> " + account.getID() + ". Your new account balance is $"
+ account.getBalance() + "\nYou will accrue monthly interest at a rate of "
+ account.getMonthlyInterestRate() + "%");
System.out.println("\nThank you for banking at the Bank of Rob. Have a good day.");
}
}




class Account {
/**declare variables*/
private int id;
private double balance;
private double annualInterestRate;
private double monthlyInterestRate;
private double withdraw;
private double deposit;
private double ODLimit;
/**Default constructor*/
public Account() {
}
public Account(int id, double balance, double annualInterstRate) {
this.id = id;
this.balance = balance;
this.annualInterestRate = annualInterestRate;
}
public Account(double balance, double ODLimit) {
this.balance = balance;
this.ODLimit = ODLimit;
}
/**set an id*/
public void setID(int id) {
this.id = id;
}
/**return id*/ public int getID()
{
return id;
}
/**return balance*/
public double getBalance() {
return balance; }
/**set new balance*/
public void setBalance(double balance) {
this.balance = balance; }
/**setting annualInterestRate*/ public void setAnnualInterestRate(double annualInterestRate) {
this.annualInterestRate = annualInterestRate; }
/**return annualInterestRate*/ public double getAnnualInterestRate() {
return annualInterestRate; }
/**find monthly interest rate*/ public double getMonthlyInterestRate() {
double monthlyInterestRate = annualInterestRate / 1200;
return monthlyInterestRate; }
/** deposit amount*/
public void deposit(double amount) {
balance +=amount; }
/** withdraw amount*/
public void withdraw(double amount) {
balance = balance - amount; }}




//ChequingAccount.java - chequing account... with overdraft limitpublic
class ChequingAccount extends Account {private double ODLimit;
private double balance;private double amount = 30000;public ChequingAccount() { super();
balance = 0;
ODLimit = 0;}public ChequingAccount(double balance, double ODLimit) {
super(balance, ODLimit);
this.ODLimit = 5000;
this.balance = 20000; }
/**return balance*/
public double getODLimit() {
return ODLimit; }
/**set new balance*/
public void setODLimit(double ODLimit) {
this.ODLimit = ODLimit; }
/** Valid withdraw amounts must be less than the account balance + the limit */ public void withdraw(double amount) {
if (amount <= (balance + ODLimit))
balance = balance - amount;
else
System.out.println("You withdrew too much and exceed the overdraft limit"); }}
[[code]]
