This is a follow up on my previous question "A grid and a menu walked into a program"
I integrated Classes into the mix.
The program now asks how big you want the grid to be.
Code
import java.util.Arrays;
import java.util.Random;
import java.util.Scanner;
class NumberGrid {
private sta...
private static final int RANDOM_NUMBER = 10;
Everyone knows the true random number is 4.
Less jokingly, what's the RANDOM_NUMBER for? Consider adding comments to explain the purpose of your variables... or better yet renaming them (to RANDOM_NUMBER_MAX, perhaps).
static Random rand = new R...

What is you approach to unit test such contract.
public Stack<T>{
void push(T object);
void T pop();
int size();
}
How should you test your size() and pop() in order to prevent bugs(underlying data structure in not being cleaned) in implementation like below:
public StackImpl im...

Interactions
In addition to dividing the application into three kinds of components, the model–view–controller design defines the interactions
between them.
A controller can send commands to the model to update the model's sta...
I recently realized that a new limitation has been introduced to comments that prevents us from starting with +1 or -1 (or at least it's somewhat new -- earliest mention I can find is a post from November 2014). You get the below message:
I disagree with this for many reasons, all which appear...
This change was certainly... controversial. It's been running for about two months now, and I've collected quite a bit of data. I liked the stats Kendra put together from the initial set of data, so I tried to collect some similar aggregate numbers for the full two months:

The plan is to call this class from a controller/view handling the "dashboard" on our Intranet page.
Is there any way I could optimize the class? should the...
I'm looking for some hints or advises regarding efficiency, performance and some good coding practices. Also I'm curious about synchronization. The server is multithreaded, so I think some operations should be synchronized.

Field Visibility
Restrict field visibility as much as possible. Use private final
Using this. in constructor
In your constructor, you can use this. to assign your fields. This will allow you to use the same parameter name as field name. For example:
public NumberGrid(int numberRows, int num...

I'm currently learning to write my first jquery plugin for a custom slider. For now, I'm halfway there, but it seems it doesn't bind any of my events.
I'm trying to wrap my head around why I can't seem to bind my 'keyup' and 'mousewheel' events. Of course my plugin is depending on the Jquery mo...
There isn't much to pick on, really - code is clean, naming is unambiguous, scopes all have their braces, you're yielding enumerables, comments are useful, and you even have XML documentation everywhere... I can't find anything in the code itself that's off-putting, confusing, or just wrong. Noth...
First post!
I have a WPF C# application that I want to move to a MVVM pattern.
My first step is to remove the button click handlers from the code behind of the UI.
I've found some exmaples online and then modified them to my needs. Is the following code a good way to use buttons without the co...
