I apologize to many who have said good things about Java for not pinging them all, first. Etiquette says I should...
If your application requires SPEED, or is an application that will be opened and left open for long periods of time, you MUST NOT use Java. I have found that ALL of the programs on my computer that use Java eat more and more time and memory all the time. Many of those programs I like, but I find I have to eventually purge them from the system, which is often not convenient. Quite a few programs look great when I fire them up and test them, and as long as I don’t put too much of a demand on them, they perform OK. However, when I start using them in a professional type sense, the time penalty explodes in at least a quadratic manner with the data requirements. Often, they bog down so much that I have to kill them using the task manager to get use of my computer back. If you are only going to be using short lists of data and have limited time requirements the program will be used, Java may be fine.
I’m not familiar with C#, and Python may have some of the same limitations as Java, though I’m not as familiar with that.
Ditto. Java is the pits.
I’d use C# since I’m using it right now. C# or VB about the same, since both mean .NET stuff. But Desktop generally means a lot of UI. C# and VB do that easily.
If it’s a massive and complex app with performance issues I’ll use C++. I haven’t used python, so no can say.
