Hi there,
I did this program, but, im having problems with attaching the events. i want the total bill amount to be calculated when i click the ‘OK’ button, and i need it to be displayed in the window. The problem is that I dont know why I dont get why its not adding the total bill of what i selected. It only displays "Total: 0"
im assuming that:
Sandwich = $2 per unit
Tea – $1 per unit
Coke – $1 per unit

I have this program right now, but I need to modify it to output to the JTextPane.
What I mean is, when someone clicks on the 1 button, it needs to output to the TextArea a 1. None of the add, subtract, multiply, divide symbols need to....just the numbers and the decimal point. I have no idea how to do this. Can anyone help me? Here's the program.

Hi people,
I am just learning java.I have been creating a project which involves JDBC Connectivity.I find that the statements,
String string_dob=text_dob.getText();
//Converting string to date
System.out.println(string_dob);
s.Info_DOB=Date.valueOf(string_dob);
runs perfectly fine in the method insert() and throws up an illegal Exception in the method UPDATE.This is the error I get when I pass a date "1979-05-02"

The question is how can I update the JTextField in Class CreditDisplayField when I hit the button in class CreditButton? I wrote in a test printing to console to make sure the "logic.addCredits();" in the class ButtonHandler is being done and that works but the "creditDisplay.update();" in the same area still shows 0 and does not update w/ the added amount of credits. This was originally a homework assignment that I completed in 3 very large...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:

In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
