There are several Eclipse downloads on the Eclipse site that I should choose?
This is the Eclipse IDE for Java EE Developers
This is Eclipse Classic 3.7.2
Or is it the Eclipse IDE for Java Developers
Now I am programming regular Java applications, 2d graphics (awt, graphics2d, etc.) and in the future JSP.
For general Java programming, Eclipse Classic is appropriate.
If you want to do web development, I suggest a Java EE variant that is suitable for JSP (it also contains everything that the classic version does).
Select the Eclipse IDE for Java Developers. He does everything except JSP. When you reach the stage where you want to work with JSP, you can just upgrade your Eclipse and add EE features.
Any of the packages will run "regular Java programs" and "2d". "3D" will require additional libraries that can be added to any offer; but, "jsp" will be much easier to develop with Java EE offerings.
It looks like you're going to surf the web in the future. I offer an EE version (enterprise version)
I offer you the second option, that is, the Eclipse IDE for Java EE developers, because if in the future you want to develop a web application, then it will be useful.
