I've been working with the java.util.prefs.Preferences functionality (in Java 8, on a Windows machine). And it works, where I can write new keys to the Windows Registry. So, I use Preferences.systemRoot() to get the Preferences object for the system, and then use the node() method to get a Pref...
I have written code to send a simple email submission form to a sql table so that I can manage the data. I would like feedback on whether or not the code that I have written is efficient and secure. I have a config file that defines constants for database credentials.

An optimisation question:
Currently I have entities stored in text files in the following format:
Attribute1,Attribute2,Attribute3
Value1-1,Value1-2,Value1-3
Value2-1,Value2-2,Value2-3
Value3-1,Value3-2,Value3-3
And convert it into a 2D array in the following format:
$array = array(array('At...

However, I run into a strange error when I try to install the library to my system.

I am trying to Modify the Month class in Figure by assing a second constructor that, given a month name, correctly initializes the members myName and myNumber. The constructor should validate the month name. Write a test program that tests the correctness of your modified Month class.

There a few subtle differences between the BSD cp that Mac uses and the GNU cp of most linux distributions.
Consider the following snippet of man cp from a linux box:
-d same as --no-dereference --preserve=links
-P, --no-dereference
never follow symbolic links in SOURCE

when an prospective employer asks you a question like this one, they most likely want to see something original, they want you to show them that you can create code and not just copy and past bits and pieces of code.
if what you wrote works and runs correctly then you have accomplished the answe...
IMHO this is exactly why C# requires the ref keyword to be specified at the caller, so that you know when you're passing that parameter, that the method can modify it.
Now this is valid for value types. Doing that for reference types is a slippery slope I find, if your intention is to modify a p...
I am embedding my size in a Stream in the first 4 byte. When I think about it, it should be possible to do it better, but that depends.
Here is how I currently do it:
bsize = ms.Length;
tcp.GetStream().Write(BitConverter.GetBytes(bsize), 0, intsize);
tcp.GetStream().Write(ms.GetBuffer(), 0, (i...
The following is from one of my latest half-baked attempts at pretending to be a java coder:

If you already have a separate function for printing the arrays, then you should have others to do the sorting. A function should be responsible for doing one thing, which is essential in maintaining separation of concerns. This will also make the program easier to maintain as each segment will...
My story is similar to @Syb0rg's. I mean, I started off as a driver-by too. I joined April 4th, 2013, and posted 7 questions between April 10, 2013 and September 5, 2013, before I posted my first answer.
By then I had reached 2K on Stack Overflow, and felt more inclined to get into this "code re...

I would like to put the following design to your consideration. This is the pattern I use to follow when I'm building a Model and Data Access Layer for an MVC Application (using Entity Framework 5). I'm looking for any advises about how to improve me design (feel free to provide a new one) becaus...
The following is a small class I extended MySQLi. I'm going to use this in my upcoming projects, but my main reason to do this class is learning, so I would like to submit this for your review, tell me if there are any bugs or improvements to be made.

I know about prepared statements, ...

I'm not suggesting there are any currently on the site (there may be, may be not), but it occurs to me that there's the distinct possibility.
On StackOverflow, as example, an unanswerable question would have to be a question where the posting user essentially lied about the actual results. On S...
