I have wrote this program over and over again, can someone please tell me what I am missing, it looks like its a small error I am not catching.

Here is what I am trying to accomplish:

Design a class named Account that contains:

  • A private int data field named id for the account(default 0)
  • A private double data field named balance for the account (default 0)
  • A private double data field named annualInterestRate that stores the current interest rate (default 0). Assume all accounts have the same interest rate.
  • A private Date data field named dateCreated that stores the date when the account was created. A no-arg constructor that creates a default account.
  • A constructor that creates an account with the specific id and initial balance.
  • The accessor and mutator methods for id, balance, and annualInterestRate.
  • The accessor method for dateCreated
  • A method named getMonthlyInterestRate() that returns the monthly interest rate.
  • A method named withdraw that withdraws a specified amount from the account A method named deposit that deposits a specified amount to the account.
  • Write a test program that creates an Account object with an account ID of 1122, a balance of $20,000, and an annual interest rate of 4.5%. Use the withdraw method to withdraw $2,500, use the deposit method to deposit $3,000 and print the balanace, the monthly interest, and the date when this account was created.

Here is what I have so far:

import java.util.Date;

public class Assign22 {

public static void main(String[] args) {
    // TODO Auto-generated method stub

Account account1 = new Account(1122, 20000, .045);
account1.withdraw(2500);
account1.deposit(3000);
System.out.println("Date Created:" + java.util.Date dateCreated = new java.util.Date());
System.out.println("Account ID:" + account1.id);
System.out.println("Balance:" + account1.getBalance());
System.out.println("Interest Rate:" + account1.getAnnualInterestRate());
System.out.println("Balance after withdraw of 2500:" +       account1.getAnnualInterestRate());
System.out.println("Balance after deposit of 3000:" + account1.getAnnualInterestRate());
System.out.println("Monthly Interest:" + account1.id);

System.out.println("Process completed.");
}

class Account {
//define variables
private int id;
private double balance; // balance for account
private double annualInterestRate; //stores the current interest rate
private Date dateCreated; //stores the date account created

//no arg construtor
Account () {
    id = 0;
    balance = 0.0;
    annualInterestRate = 0.0;
}
//constructor with specific id and initial balance
Account(int newId, double newBalance) {
    id = newId;
    balance = newBalance;
}
Account(int newId, double newBalance, double newAnnualInterestRate) {
    id = newId;
    balance = newBalance;
    annualInterestRate = newAnnualInterestRate;
}
//accessor/mutator methods for id, balance, and annualInterestRate
public int getId() {
    return id;
}
public double getBalance() {
    return balance;
}
public double getAnnualInterestRate() {
    return annualInterestRate;
}
public void setId(int newId) {
    id = newId;
}
public void setBalance(double newBalance) {
    balance = newBalance;
}
public void setAnnualInterestRate(double newAnnualInterestRate) {
    annualInterestRate = newAnnualInterestRate;
}
//accessor method for dateCreated
public void setDateCreated(Date newDateCreated) {
    dateCreated = newDateCreated;
}
//define method getMonthlyInterestRate
double getMonthlyInterestRate() {
    return annualInterestRate/12;
}
//define method withdraw
double withdraw(double amount) {
    return balance -= amount;
}   
//define method deposit
double deposit(double amount) {
    return balance += amount;   
}
}

}

This is the error that I am receiving: Not sure what I missed here:

"Syntax error on token "Date", , expected after this token dateCreated cannot be resolved to a variable at Assign22.main(Assign22.java:12)"

You can't have variable declarations as part of String concatenation expressions

System.out.println("Date Created:" + java.util.Date dateCreated = new java.util.Date());

Split that up

java.util.Date dateCreated = new java.util.Date()
System.out.println("Date Created:" + dateCreated);
