hello,
I have an app that pops up a custom dialog box and one of the fields for
user input is an account balance field. The data gets put into an
Object and eventually into an instance of DefaultListModel. When I use
getText() on the field I pass it to Double.parseDouble to convert it so
I can store it as a number and not a string. When I display it (either
in the list or in the dialog box) I want it to be displayed using
currency...

Okay, I finally got this program to run according to what the book had us build it as. Now prof wants case 2 and case 3 to prompt again for input, check input to see if it is the correct type, then display a "correct" message if is correct.
So, If you choose 2 from the original pane, you would be prompted to enter an integer. The program would check to see if you input an integer and if it was then you would get a "correct" message. If not...

Write and test the following method that implements the power function:
static double pow(double x, int n)
This method returns the value of x raised to the power n. For example pow(2.0, -3) would return
2-3 = 0.125
For each value of pow(x,n) that you print, also print the value of Math.pow(x,n) to check your results.

I need to validate a string before I use the Double.parseDouble() method to assign a value in the code below.
Code: Java
String s="";//s can be a string read from the keyboard
//double validation
double w=Double.parseDouble(s);

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:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

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,...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....
Now, this would greatly impact the work of software developers. The idea...
