If you want to illustrate your skillset, post decent articles here and cite them during an interview. Your app doesn't have to be ground-breaking, but must illustrate a solid understand of what you're doing, and why you're doing it the way you're doing it.
One way to accomplish this is to find an application, and duplicate it to the extent possible. I do this all the time to learn new frameworks and different languages. For instance, to teach myself C# and .Net, I wrote his application:
".45 ACP - because shooting twice is just silly" - JSOP, 2010 ----- You can never have too much ammo - unless you're swimming, or on fire. - JSOP, 2010 ----- When you pry the gun from my cold dead hands, be careful - the barrel will be very hot. - JSOP, 2013
My name is Willem. I am a teacher and decided to do the OCA exam. I teach computer literacy and hope to teach Information Technology to our high school students.
Is there a reputable site that offers free VCE exams that I can use to prepare for the exam. Please also recommend paid sites. I found a few, but paying around $50 for just one exam with roughly 70 questions seems a bit extreme.
Because thread p3 is the last to be started. Your code is not a valid test of anything useful. Thread priority only works in a long running process when you have parallel threads contending for the CPU. All you have is three threads, which run sequentially one after the other, perform a single very simple task and terminate. So there is no point at which the system has to make any decision as to which one should be active.
Don't post this here - if you got the code from an article, then there is a "Add a Comment or Question" button at the bottom of that article, which causes an email to be sent to the author. They are then alerted that you wish to speak to them.
Posting this here relies on them "dropping by" and realising it is for them.

I was looking at the code for a tictactoe game the other day and saw something that confused me.
The X and O were called Pegs. They were not called X and O out right. They were just trying to put down code that simulated players taking turns placing a Peg. The game would switch between first player and second player turn:
As you can see, the variable Peg was used as a type declaring different things. It was used as an enum, an array, as methods. My question is how. There is no class Peg anywhere in the code so how is Peg being used as some king of data type?
Peg is an enum only, and can have one of the values NONE, FIRST, SECOND. The statement
private Peg cells = new Peg[SIZE][SIZE];
declares the variable cells as an array of Pegs, it does not declare Peg as an array type. Similarly the two method definitions are not defining Peg as the method, but as the return type, from the methods with the names checkRowMatch and checkColumnMatch. As you can see in each case the method returns a Peg enumeration value.
If DatePicker receives a value, then it will be stuck with that value, even if you remove the date text from it's TextField, or even if you write a text that isn't date format (random characters). Is there a way to tell it to change it's value to null, if the text from TextField is removed or if the text isn't date format (ex: "adasda" instead of "10.10.2010")?
Automatic vehicle license plate recognition is an important component of modern intelligent transportation systems (ITS). Generally vehicle license plate recognition is divided into several steps including license plate extraction, image region which contains a license plate, character segmentation, and character recognition. Automatic license plate recognition system using Camera mounted over the exposure system image of the license plate is captured and the image is processed to extract the license number.
On my workstation the program I made is running well, but here I have Java JDK installed.
When I was done and tried to run it on a different machine, the program starts, and for a split second the GUI shows then the whole program closes itself. After some testing, I found out that the problem somehow is Java JDK.
If I install Java JDK on the testing machine, the program runs fine, even if I uninstall Java JDK after that, the program still runs, which makes me think it might add additional jars in Java folder. If I uninstall Java, and reinstall only java, the program again won't work unless I install Java JDK too.
Did anyone encountered this problem too, or knows a fix for it? Am I right about JDK actually adding additional jars in Java folder, which remain there even after JDK is uninstalled?
Here is a list of libraries my program uses, I marked them at the end with  because I'm using multiple classes from them and the list would have been way too long if I was to add all of them:
Also, I'm using a DLL file, but from my testing that one isn't the problem, as I said, the JDK is somehow.
Hope I explained the problem well enough, if not, I'll happily answer any other questions.
OS: Windows 10 x64 Pro on both machines.
Any Java application should run on any system that has the correct JRE loaded. Are you sure that the version of the runtime on the test machine is the same as, or later than, the one on the development system?
