And the results are:
So the Eclipse wins. Actually this doesn't supprise me, since I personally believe that Eclipse is the best free IDE for JAVA.
However, I thought that there will be more people, who use IntelliJ. Many people said in comments that IntelliJ is very good and I agree with them. Probably the price makes it less attractive.
In addition there were people, who said in comments that they are forced to use Eclipse and if they had a choice, they would have used something else.
I can only say: Shame on the managers of these people. No project should insist on using a specific IDE, but each developer should be able to choose. And the project should be maintained using the build scripts.
Anyway this survey is over.
Thank you for the participation!
