Which IT Skills Are In The Greatest Demand By Employers Between JAVA, .net, VB, And Vb.net?

The biggest problem with that is that .net limits you to microsoft technology. This is the reason why most large corporations have made a strategic technology decision in favour of Java because it can be used on all platforms (Microsoft included).

There are only two exceptions:
1. If your employer is a Microsoft partner and only uses .NET
2. If you write software focused on user interface design

Only in these two cases can I recommend you specializing in .NET.
For everything else use Java.

I would recommend you that among all of yours options, the most advance the company would prefer as the .net technology is the latest and mostly high demanded nowadays.

So if you select the .Net language then it would be best for your job the company will give preference to this language. Java is scripting language and it was used in old times and now .Net is the latest technology for websites and its development so I would recommend that the .Net is the best I have ever used. .Net is a secure and reliable when working with the web pages. It connects system, information, and people through software integrated by the Microsoft platform. It provides users security for using web services.

The Microsoft platform provides every thing that deploys and develops IT infrastructure. So as the IT industry is growing the need for developers is also growing you must check also the advertisement you can know which is the commonly used technology in your country or city because it differs from country to country some countries adopt technology very fast while others are bit reluctant in using that technology so you can find how many jobs are advertised against each AD so that you should adopt accordingly.
