// set up beverageJComboBox

CAn you help me out with it? the first one i have my combobox called:


beverageJComboBox = new javax.swing.JComboBox();


Next one is:


private void beverageJComboBoxItemStateChanged(...

Okay i got the list of what is wrong, and i get these warnings below

RestaurantBillCalculator.java:308: warning: [unchecked] unchecked call to addIte
m(E) as a member of the raw type JComboBox
...

There is no errors, this is what i don't understand! the program runs fine in Netbeans but when i run it at the command line, it asks to recompile with -Xlint

So how do i write that in the command line? the way you have it exactly or what?

If this is just a warning, why wont my code compile in the command line? i have 7 warnings but no...

Simply put, i have to run my program from the command line

My code is:



public static void main( String[] args )
{

// check command-line arguments

Although that may be helpful, i got it working, cheers anyways

Hi, Ill explain what im stuck on,
I have a class that extends JFrame, within that, i have set up JPanel where within that i have four JComboBoxes, I am to enable this JPanel and its JComboBoxes at...

forget it, got someone else helping me

Its alright, i have it working now, thanks

This is what i have done:


private double calculateSubtotal()
{
double total = 0;
String[] items = billItems;

try
{

No i haven't, problem is i keep find examples with No argument constructors like this:
code not executing (Beginning Java forum at JavaRanch)

My constructor has two-arguments: public...

Can i just add to your post here and say that there was supposed to be two // in front of anonymous inner class, typo problems sorry

This is the rest of the question: This method should then calculate the total price of all the items in the ArrayList and return this value as a double.

Probably doesn't help?

Having trouble figuring out the code in order to find the price column for all items in a ArrayList

so far i have:


private double calculateSubtotal()
{

try
{

Good practice in a sense that when I am positioning components
such as Jcomboboxes i can position stuff with setBounds

Prob any other time I would not use it and my lecturer would
prob say...

I just don't have the time I'm afraid, Hence I'm asking all of this, any
Other day of the week I would listen and would never use null layout
I've asked my lecturer now to figure out this problem

Unfortunately i have to use Null Layout, lecturer wants it for good practice purposes

After messing around with it a lot i finally got it working, its fairly similar to what you said except i need it to be associated with the ArrayList billItems

:) I aware ItemEvent.selected does not exist, i should have spelt it correctly sorry and also thanks, ill give it a go.

That's what i am asking for, how do i do the LISTENER inside that method? all i want is an example of how to do the ItemEvent.selected within beverageJComboBoxItemStateCHanged method. I am not not...
