What is a UserAccount? I guess it's supposed to be a class but the compiler can't find a class definition for a UserAccount.

kind regards,

HI Jos

In my viewBalance() method in class accounAR I am having issues referencing the getBalance method in accounts so I added Account UserAccount = new Account (); to the instance variable of accountAR.

Im new to this and obviously doing things wrong. My account class is below.

import java.util.*;

public class Account {


private int id;
private String name;
private double balance;
private int pinNumber;
private boolean isActive;
private Date dateCreated = new Date();
private double annualInterestRate;



public Account (int a ) {

int id = a;
String name ;
double balance;
int pinNumber = 1386;
boolean isActive = false;
Date dateCreated = new Date();
double annualInterestRate = 4.4;

}

// no agr constructor
public Account (){};


// set the pinNumber
protected void  setpinNumber (int input) {
this.pinNumber = input; }

protected void setId (int inputID) {
	this.id = inputID;}

protected int getpinNumber () {
return pinNumber;
}


protected boolean testID ( int entry) {

if ( id != entry  ) {
isActive = true ;
}
else
{
System.out.println (" Please re-enter your PIN number");
isActive = false;

}
return isActive;

}


protected int getid () {
return id;}


protected String getname () {
return name;}


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

protected  double getbalance () {
return balance;}

protected boolean isActive () {
return isActive;}

protected  void deposit( double amount )
	{
		balance += amount;
	}

        public double withdraw( double amount )
	{
                // See if amount can be withdrawn
		if (balance >= amount)
		{
			balance -= amount;
                        return amount;
		}
		else
                // Withdrawal not allowed
                        return 0.0;
	}

	protected void setannualInterestRate( double rate) {

 		annualInterestRate = rate ;
		}

// int for the 12 months of the year

public double m  = 12;

 // method to get the monthly interest rate

	protected  double getmonthlyInterestRate() {
	 return annualInterestRate / m ;

	    	}

protected Date getDate () {
	return dateCreated ;}

I am having issues

If you are getting errors, please copy the full text of the message and post it here.

[Tolls]

UserAccount[] UserAccountT = new UserAccount [10];
UserAccountT [0]= new UserAccount ();

What class is UserAccount?
It's not the class you just posted...

[r1b]

I have edited the code to remove UserAccount. I have added an array of Account but I am now getting the error.

[r1b]

I have got it to work by changing the Account to Accounts. The question I have now is how do I get viewBalance method () to
show the balance of array Account[0]?

[Norm]

show the balance of array Account[0]

Do you mean the contents of the one element at index 0
or the contents of the whole array?
For the whole array the Arrays class's toString() method will format the array's contents into a String.

[r1b]

It would be the balance of one element. The system prompts the user to enter an id.
If the id is entered incorrectly the user will be asked to enter a correct id. Once the id is accepted the main menu is
displayed. You can enter a choice 1 for viewing the current balance, 2 for withdrawing money, 3 for depositing money and 4 for exiting the main menu.

If the user tries to withdraw more money than is available the program reports a “ Not enough funds” message. Once you exit the system will prompt for an id again. So once the system starts, it will not stop.

[Norm]

It would be the balance of one element

Not sure what your problem is. If you have the index to the array, you can use that index to get the element.
If you have the element then you can get the balance of that element.

Please explain where your problem is.

[r1b]

Well the problem I am having is the users input is not showing the balance of the array element just created when mainMenu() called.

[Norm]

the users input is not showing the balance of the array element just created

Try debugging your code by printing out the user's input when it is first read in and then again when the code that uses that input is trying to access the array element. Is the value the user input being lost?

[Tolls]

You've got an Account in accountAR which is what is being used by the mainMenu stuff to display balances.
This has no balance.
This is not one of the Accounts in the array created in the main() method.

[r1b]

So this account I have in accountAR is showing the balance? Should I add the array of accounts to accountAR instead of main?

I tried this before but got an error telling me to add ']' but I had

Account[] acc = new Account [10];
acc [0] = new Account ();

[Norm]

Is account a subclass of Account?
Case is VERY important.

[r1b]

So this account I have in accountAR is showing the balance? Should I add the array of accounts to accountAR instead of main?

I tried this before but got an error telling me to add ']' but I had

Account[] acc = new Account [10];

Sorry this is what I had entered.

[Norm]

If you defined your array of Account objects outside of the main() method, then all the methods in the class could see and use it. You can still assign values to the elements of the array inside the main method.

[r1b]

I am getting this error now for changing the code to this.

import java.util.*;

class accountAR {


Account[] Accounts = new Account [10];
Accounts [0] = new Account();
Scanner input = new Scanner(System.in);

']' expected
';' expected
illegal start of type
<identifier> expected
';' expected
illegal start of type
<identifier> expected


all on line 7 which is Accounts [0] = new Account();

[Norm]

Line 7 belongs in a method.

[r1b]

sorry could you explain that a little more? Do I create a setAccount method?
