Thread: Can't get my program to work!! Please help!

Hello! 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)"

I thought that I created the variable here. Is it created incorrectly?

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

Check the syntax of the line where the error is. It looks weird.

So here is the output that I want:

Date Created: Fri May 16 09:33:15 EDT 2014
Account ID: 1122
Balance: 20000.0
Interest Rate: 0.045
Balance after withdraw of 2500: 17500.0
Balance after deposit of 3000: 20500.0
Monthly Interest: 76.875

Process completed.


Now that I have gotten my program to compile, how do I do math operations? I want to include the balance after withdraw, and deposit, what do I call here. I also want to create a space between Monthly Interest line, and process completed. I think I might be using the wrong terminology. Please help, this is my code:

public class Assing22 {
 
	public static void main(String[] args) {
		Account account = new Account(1122, 20000, .045);
		account.withdraw(2500);
		account.deposit(3000);
		System.out.println("Date Created: " + account.getDateCreated());
		System.out.println("Account ID:" + account.id);
		System.out.println("Balance:" + account.getBalance());
		System.out.println("Interest Rate:" + account.getAnnualInterestRate());
		System.out.println("Balance after withdraw of 2500:");
		System.out.println("Balance after deposit of 3000:");
		System.out.println("Monthly Interest:" + account.getMonthlyInterest());
 
 
		System.out.println("Process completed.");
 
 
	}
 
}
class Account {
public int id;
public double balance;
public double annualInterestRate;
public java.util.Date dateCreated;
 
public Account() {
dateCreated = new java.util.Date();
}
 
public Account(int id, double balance, double annualInterestRate) {
this.id = id;
this.balance = balance;
this.annualInterestRate = annualInterestRate;
dateCreated = new java.util.Date();
}
 
public int getId() {
return this.id;
}
 
public double getBalance() {
return balance;
}
 
public double getAnnualInterestRate() {
return annualInterestRate;
 
}
 
public void setId(int id) {
this.id =id;
}
 
public void setBalance(double balance) {
this.balance = balance;
}
 
public void setAnnualInterestRate(double annualInterestRate) {
this.annualInterestRate = annualInterestRate;
}
 
public double getMonthlyInterest() {
return balance * (annualInterestRate / 12);
}
 
public java.util.Date getDateCreated() {
return dateCreated;
}
 
public void withdraw(double amount) {
balance -= amount;
}
 
public void deposit(double amount) {
balance += amount;
}
 
}

Where the lines prints: "Balance after withdraw of 2500: I want it to say 17500.0, what math operations to do I do, to get the original balance of 20500 to subtract 2500 from the withdraw, I create a method for them.

Use the math operators: +,-,*,/ with some numeric operands as required. Assign the results to a variable.

I also was able to get the blank line printed with your help, thanks!

What does the program print out now?

BTW The code in the Account class needs formatting. Nested statements should be indented like they are in the main() method.
