Account class
I'm supposed to override the withdraw method so I can do the overdraft in the checkings account.
import java.util.Date;
//Create the class and define the variables needed
public class Account {
private int id;
protected static double balance;
private double annualInterestRate;
private Date dateCreated;
//Constructor with no arguments that creates a default account
Account(){
id = 0;
balance = 0;
annualInterestRate = 0;
dateCreated = new Date();
}
//A constructor that takes in parameters and does a couple of operations.
Account(int newId, double newBalance, double newAnnualInterestRate) {
id = newId;
balance = newBalance;
annualInterestRate = newAnnualInterestRate;
dateCreated = new Date();
}
//All the accesors used for the different variables
public int getId() {
return id;
}
public double getBalance() {
return balance;
}
public double getAnnualInterestRate() {
return annualInterestRate;
}
public Date getDateCreated() {
return dateCreated;
}
//All the mutators used for the different variables
public void setNewDate(Date newDate) {
dateCreated = newDate;
}
public void setId(int newId) {
id = newId;
}
public void setBalance(double newBalance) {
balance = newBalance;
}
public void setAnnualInterestRate(double newAnnualInterestRate){
annualInterestRate = newAnnualInterestRate;
}
//Method used to return the monthly rate and the monthly balance accordingly
public static double getMonthlyInterestRate(double annualInterestRate) {
double monthlyRate = 0;
monthlyRate = annualInterestRate / 12;
monthlyRate = monthlyRate * balance;
return monthlyRate;
}
//Method used to withdraw money
public void withdraw(double wd) {
balance = balance - wd;
}
//Method used to deposit money
public void deposit(double dp) {
balance = balance + dp;
}
}
Savings account class
I'm not sure why we there is a savings account as it does the same thing as the withdraw method.
//import javax.swing.JOptionPane;
public class savingsAccount extends Account {
public void withdraw(double wd) {
balance = balance + wd;
}
}
Checkings accounts class
It's supposed to allow the user to withdraw more than their balance with the limit being -500
public class checkingAccounts extends Account {
public checkingAccounts(){
}
}
