BankTransaction cannot be resolved to a type

robinbredin · 24 Sep 2009 at 11:04

Can't get my head round this. It's either a typo or a problem, can anybody have a look.

import javax.swing.JOptionPane;
public class classpractice7_1 {
public static void main(String[] args) {
String response;
String moreBankingBusiness;

moreBankingBusiness = JOptionPane.showInputDialog
( "Do you want to do some banking?" );
moreBankingBusiness = moreBankingBusiness.toUpperCase();
while (moreBankingBusiness.equals ("YES")){
response = JOptionPane.showInputDialog
( "What would you like to do?" +
"(1=Deposit, 2=Withdraw, 3=Get Balance)");
if (response == null)
{
JOptionPane.showMessageDialog
(null, "You clicked on the Cancel Button");
System.exit (0);
}
else
if (response.equals(""))
{
JOptionPane.showMessageDialog
(null, "You must make an entry in the InputBox");
System.exit (0);
}
else
if (Integer.parseInt(response) < 1 | Integer.parseInt(response) > 3)
{
JOptionPane.showMessageDialog
(null, response + " - is not a valid student type");
System.exit (0);
}
if (Integer.parseInt (response) == 1){
BankTransaction transaction = new BankTransaction();
transaction.makeDeposit();
}
if (Integer.parseInt (response) == 2){
BankTransaction transaction = new BankTransaction();
transaction.makeWithdrawal();
}
if (Integer.parseInt (response) == 3){
BankTransaction transaction = new BankTransaction();
transaction.getBalance();
}
moreBankingBusiness = JOptionPane.showInputDialog
( "Do you have more banking business?" );
moreBankingBusiness= moreBankingBusiness.toUpperCase();
} // end of while

JOptionPane.showMessageDialog
(null, "Thanks for banking with us!");
}
}

Where do you define the class BankTransaction??

robinbredin · 24 Sep 2009 at 11:38

I did try putting, 'String BankTransaction', but that would not work.

SimonCHere · 24 Sep 2009 at 11:49

But if BankTransaction isn't a class it wont have the makeWithdrawal() methods or any functionality. Putting 'String BankTransaction' wont help.

I do like the way you've copied and pasted some other code though

Code:

"What would you like to do?" +
"(1=Deposit, 2=Withdraw, 3=Get Balance)"

...

response + " - is not a valid student type");

na, never copied and pasted that, that's mine. BankTransactions is a class, that's why I put the other methods in, ie getBalance etc. But it should work.

SimonCHere · 24 Sep 2009 at 13:38

I just meant that you prompt for banking stuff and then respond with not a valid student type.

In that case back to slylittlefox's question:
"Where do you define the class BankTransaction?? "

robinbredin · 24 Sep 2009 at 16:13

I think I was pushing my luck with the 'BankTransactions', were I would be better off just doing this, I know this works.

if (Integer.parseInt(response) == 1) {
makeDeposit();
}
if (Integer.parseInt(response) == 2) {
makeWithdrawal();
}
if (Integer.parseInt(response) == 3) {
getBalance();
}

This is an program i did a few weeks ago, and this compiles with no problems,

Jeez, if you're going to post all that amount of code at least use the

Code:

 tags so it's readable.

SimonCHere · 25 Sep 2009 at 09:17

OK, so I don't do java but in your original you will need something like this:

Code:

public class BankTransaction {
  public static void makeDeposit() {
    //make deposit stuff
  }
  public static void makeWithdrawal() {
    //makeWithdrawal stuff
  }
  public static void getBalance() {
    //getBalance stuff
  }
}

Do you have something like that?

Hi There is a few errors lines under Banktransactions for withdrawal

Code:

import javax.swing.JOptionPane;
public class classpractice7_1 {
          public static void main(String[] args) {
          	String response;
          	String moreBankingBusiness;
          	
          	
          	moreBankingBusiness = JOptionPane.showInputDialog
			  ( "Do you want to do some banking?" );
          	moreBankingBusiness = moreBankingBusiness.toUpperCase();
          	while (moreBankingBusiness.equals ("YES")){
          		response = JOptionPane.showInputDialog
				( "What would you like to do?" +
					"(1=Deposit, 2=Withdraw, 3=Get Balance)");
          	if (response == null)
          	{
          		JOptionPane.showMessageDialog
				   (null, "You clicked on the Cancel Button");
          		System.exit (0);
          	}
          	else
          	if (response.equals(""))
          	{
          		JOptionPane.showMessageDialog
				  (null, "You must make an entry in the InputBox");
          		System.exit (0);
          	}
          	else
          	if (Integer.parseInt(response) < 1 | Integer.parseInt(response) > 3)
          	{
          		JOptionPane.showMessageDialog
				    (null, response + " - is not a valid student type");
          		System.exit (0);
          	}
 public class BankTransaction {
          public static void makeDeposit() {
          }
 }
           
          	if (Integer.parseInt (response) == 1){
          		BankTransaction transaction = new BankTransaction();
          		transaction.makeDeposit();
          	}
          public static void makeWithdrawal() {
            if (Integer.parseInt (response) == 2){
          		BankTransaction transaction = new BankTransaction();
          		transaction.makeWithdrawal();
          		
          		}
          	}
          public static void getBalance() {
          	 if (Integer.parseInt (response) == 3){
          		BankTransaction transaction = new BankTransaction();
          		transaction.getBalance();
          	}
          	moreBankingBusiness = JOptionPane.showInputDialog
			   ( "Do you have more banking business?" ){
          	moreBankingBusiness= moreBankingBusiness.toUpperCase();
          	}  
          	
          	JOptionPane.showMessageDialog
			  (null, "Thanks for banking with us!");
          } 
}

After I ran that i got this here,

Code:

Syntax error, insert "}" to complete Block
	Syntax error, insert "else Statement" to complete IfStatement
	Syntax error, insert "}" to complete Statement

	at classpractice7_1.main(classpractice7_1.java:55)
Exception in thread "main"

Oh come on, even I can work out what that means!
You have got your } in the wrong place and one too many.

Code:

public static void makeDeposit() {
  [COLOR="Red"][B]        }
 }[/B][/COLOR]
           
          	if (Integer.parseInt (response) == 1){
          		BankTransaction transaction = new BankTransaction();
          		transaction.makeDeposit();
          	}

Also, am I helping you with your home work or something as I think you need to go back to basics.
the bits you have

Code:

public static void main(String[] args) {
	String response;
	String moreBanKingBusiness;
	moreBanKingBusiness = JOptionPane.showInputDialog("DO you want to do some banking?");
	moreBanKingBusiness = moreBanKingBusiness.toUpperCase();
	while (moreBanKingBusiness.equals ("YES")){
		response = JOptionPane.showInputDialog("What would you like to do?, (1=Deposit, 2=Withdraw, 3=Get Balance)");
		if (response == null)
		{
			JOptionPane.showMessageDialog(null, "You clicked on the Cancel button");
			System.exit (0);
		}
		else If (response.equals(""))
		{
			JOptionPane.showMessageDialog(null, "You must make an entry in the InputBox");
			System.exit (0);
		}
		else if (Integer.parseInt(response) < 1 | Integer.parseInt(response) > 3)

			JOptionPane.showMessageDialog(null, response + " - is not a valid banking function");
			System.exit (0);
		}

			BankTransaction transaction = new BankTransaction();
                        transaction.makeDeposit();

			BankTransaction transaction = new BankTransaction();
                        transaction.makeWithdrawal();

		moreBanKingBusiness = moreBanKingBusiness.toUpperCase();
		
	} //end of while loop
	
	JOptionPane.showMessageDialog(null, "Thanks for banking with us!");
	System.exit (0);

Your right, it was done in haste, sorry

Youll be pleased to know it is not any homework. It is something I'am playing around with.
