Using One Object in Multiple Classes

I'm trying to use a setter/getter class in multiple classes to modify a single variable. I understand that I have to use the same object in order for this to work, but I'm unsure on how to make a single object accessible to multiple classes.
public class accountbalance {
private double balance;
//getter
public double getBalance() {
return balance;
}
//Setter
public void setBalance(double newBalance) {
this.balance = newBalance;
}
}
This is where I'm trying to use it first:
public class CreateAccount {
String name;
double social;
int pin;
public CreateAccount()
{
name = "null";
social = 0;
pin = 0;
}
public CreateAccount(String enteredName, double enteredSocial,int enteredPin, double value)
{
name = enteredName;
social = enteredSocial;
pin = enteredPin;
double accountnum = 87495;
accountbalance a1 = new accountbalance();
a1.setBalance(value);
System.out.println(name);
System.out.println(social);
System.out.println("Your new PIN is " + pin);
System.out.println("Your new account balance is " + (a1.getBalance()));
}
}
And then I'm trying to use it again here:
public class deposit {
double enteredAmt;
double amt;
public void deposit() {
System.out.println("Enter an amount to desposit: ");
Scanner in = new Scanner(System.in);
enteredAmt = in.nextDouble();
accountbalance ab1 = new accountbalance();
System.out.println("current balence: " + ab1.getBalance());
amt = ab1.getBalance() + enteredAmt;
ab1.setBalance(amt);
System.out.println("Your new balance is " + (ab1.getBalance()));
}
}

I believe what you're trying to do is use the Command Design Pattern.
If you changed your classes to look more like this, things might work a tad bit better.
public class Account {
// Please do not use SS for an identifier.
private String identifier;
private String name;
// Money needs to be stored in it's lowest common denominator.
// Which in the united states, is pennies.
private long balance;
public Account(String identifier, String name) {
this.identifier = identifier;
this.name = name;
this.balance = 0L;
}
public String getIdentifier() {
return this.identifier;
}
public String getName() {
return this.name;
}
public long getBalance() {
return balance;
}
public void credit(long amount) {
balance =+ amount;
}
public void debit(long amount) {
balance =- amount;
}
}
Then here would be your CreateAccountCommand. It is a bit anemic, but that is ok.
public class CreateAccountCommand {
private String identifier;
private String name;
public CreateAccount(String identifier, String name) {
// Identifier sould actually be generated by something else.
this.identifier = identifier;
name = name;
}
public Account execute() {
return new Account(identifier, name);
}
}
Here is your DepositCommand:
public class DepositCommand {
private Account account;
private long amount;
public DepositCommand(Account account, long amount) {
this.account = account;
this.amount = amount;
}
public void execute() {
this.account.credit(amount);
}
}
WithdrawCommand:
public class WithdrawCommand {
private Account account;
private long amount;
public DepositCommand(Account account, long amount) {
this.account = account;
this.amount = amount;
}
public void execute() {
this.account.debit(amount);
}
}
Then run everything:
public class Run {
public static void main(String... args) {
CreateAccountCommand createAccountCommand = new CreateAccountCommand("12345678", "First_Name Last_Name");
Account account = createAccountCommand.execute();
System.out.println(account.getIdentifier());
System.out.println(account.getName());
System.out.println("Your new account balance in pennies: " + account.getBalance());
// Deposit $100.00
DepositCommand depositCommand = new DepositCommand(account, 10000);
depositCommand.execute();
System.out.println(account.getIdentifier());
System.out.println(account.getName());
System.out.println("Your new account balance in pennies: " + account.getBalance());
// Withdraw $75.00
WithdrawCommand withdrawCommand = new WithdrawCommand(account, 7500);
withdrawCommand.execute();
System.out.println(account.getIdentifier());
System.out.println(account.getName());
System.out.println("Your new account balance in pennies: " + account.getBalance());
}
}

Trying to ask the user for input in another method

Any pointers are much appreciated.

I ran your code. I found two errors.
you have a BankAccount1 class and You refers to BankAccount. without "1".
You use a wrong path
See your path is
C:/Users/USER/workspace/assignment/data/AssignmentData
But Path should be like below
C:\\Users\\Menuka\\IdeaProjects\\JavaTest\\src\\AssignmentData`
I'll post full code below.

System.out.printIn() not working on my code

it is showing me "cannot find symbol method printIn(java.lang.string)
please what is the error, i have used 3 different IDES.
whats wrong with the System.out.printIn()
public class Account
{
private String owner;
private int balance;
public Account (String name)
{
owner = name;
balance = 0;
}
public void deposit(int anAmount)
{
balance += anAmount;
}
public int withdraw(int anAmount)
{
int amountWithdrawn;
if (anAmount <= balance )
amountWithdrawn = anAmount;
else
amountWithdrawn = balance;
balance -= amountWithdrawn;
return amountWithdrawn;
}
public void print()
{
System.out.printIn("Owner =" + owner +" Balance=" + balance);
}
}

That is not printIn(). You typed letter I for Ikea
That is println() you had to use letter l for lima

Please I would like know How would I implement JOptionPane instead of import java.util.Scanner;
I also have 4 separate classes
If i implement JOptionPane will it clean up the code I would also like to know any changes anyone would make.

Start by taking a look at How to Make Dialogs...
What you basically want is to use JOptionPane.showInputDialog, which can be used to prompt the use for input...
Yes, there are a few flavours, but lets keep it simply and look at JOptionPane.showInputDialog(Object)
The JavaDocs tells us that...
message - the Object to display
Returns:user's input, or null meaning the user canceled the input
So, from that we could use something like...
String value = JOptionPane.showInputDialog("What is your name?");
if (value != null) {
System.out.println("Hello " + value);
} else {
System.out.println("Hello no name");
}
Which displays...
Now, if we take a look at your code, you could replace the use of scan with...
public static String getInput(String inputType) {
String input = JOptionPane.showInputDialog("Enter the " + inputType + ": ");
return input;
}
As an example...
Now, what I might recommend is creating a simple helper method which can be used to prompt the user in a single line of code, for example...
public class InputHelper {
public static String promptUser(String prompt) {
String input = JOptionPane.showInputDialog(prompt);
return input;
}
}
which might be used something like...
String value = InputHelper.promptUser("Please enter the hours worked");
hours_ = Double.parse(value);
And this is where it get's messy, as you will now need to valid the input of the user.
You could extend the idea of the InputHelper to do automatic conversions and re-prompt the user if the value was invalid...as an idea

It is much easier than you think, if you try. Get used to reading the Java API.
http://docs.oracle.com/javase/7/docs/api/javax/swing/JOptionPane.html
Even has examples.
String input;
JOptionPane jop=new JOptionPane();
input=jop.showInputDialog("Question i want to ask");
System.out.println(input);

So I have an assignment in Advanced Inheritance for Java and have the code pretty much hammered out but am having issues finishing it off and making it actually display the output. The program was split into 4 different parts and I have them listed below.
Account.java

protected long accountNumber;
protected double accountBalance;
public long getAccountNumber()
{
return accountNumber;
}
public double getAccountBalance()
{

number = accountNumber;
}
public void setAccountBalance(double balance)

Is there something I'm like really obviously missing? It all compiles just fine but the output just displays 0s instead of the Account Numbers, Balance or Interest.
Any help would be very much appreciated since I'm running out of time.

All of your setter methods look the wrong way round, you've got them as...
public void setAccountNumber(long number)
{
number = accountNumber;
}
public void setAccountBalance(double balance)
{
balance = accountBalance;
}
All you're doing there is setting the parameter value, they should be...
public void setAccountNumber(long number)
{
accountNumber= number;
}
public void setAccountBalance(double balance)
{
accountBalance= balance;
}
You can make sure this doesn't happen my making your parameters final

Have a look at your constructors and setters You inverse your variable attribution
Ex
public void setAccountNumber(long number)
{
number = accountNumber;
}
should be
public void setAccountNumber(long number)
{
accountNumber = number;
}
same for all your setters and constructors
