Question

Java - Write a test program that creates an Account object with an account number of AC1111, a balance of $25,000, and an annual interest rate of 3.5. Use the withdraw method to withdraw $3,500, use the deposit method to deposit $3,500, and print the balance, the monthly interest, and the date when this account was created.

Answer 1

package add;


public class MainAcount {
        public static void main(String[] args) {
        Account account = new Account("AC1111", 25000.0,3.5);
        account.withdraw(3500.0);
        account.deposit(3500.0);
        System.out.println("Balance: $" + account.getBalance());
        System.out.format("Monthly Interest: %.2f\n" ,account.getMonthlyInterest());
        System.out.println("Date Created: " + account.getDateCreated());

    }
}


class Account {
    private String id = "";
    private double balance = 0.0;
    private static double annualInterestRate = 0.0;
    private java.util.Date dateCreated;

    public Account() {
        dateCreated = new java.util.Date();
    }

    public Account(String id, double balance,double annualInterestRate ) {
        this();
        this.id = id;
        this.balance = balance;
        this.annualInterestRate=annualInterestRate;
    }

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

    public double getBalance() {
        return this.balance;
    }

    public double getAnnualInterestRate() {
        return annualInterestRate;
    }

    public String getDateCreated() {
        return this.dateCreated.toString();
    }

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

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

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

    public double getMonthlyInterestRate() {
        return (annualInterestRate / 100) / 12 ;
    }

    public double getMonthlyInterest() {
        return balance * getMonthlyInterestRate();
    }

    public void withdraw(double amount) {
        this.balance -= amount;
    }

    public void deposit(double amount) {
        this.balance += amount;
    }
}

OUTPUT:-

Balance: $25000.0
Monthly Interest: 72.92
