Currently, I'm a long Eclipse user because my past and current companies always deal with eclipse. Recently I met some example java codes created using netbeans. I downloaded and tried Netbeans 7.x and 6.9.x, but they're more heavier and eating memory resources than Eclipse Indigo.

So anyone know which past version of Netbeans IDE that has lightness almost equal to or better than Eclipse Indigo (3.7) but can support Java SDK v1.6?

It doesn't matter which IDE you use. Import the project into Eclipse. – Zach Latta Jan 13 '13 at 8:28
I can't do that from eclipse. Also the netbeans project is java EE web project. I don't think java EE projects in both eclipse and netbeans are compatible each other. – suud Jan 13 '13 at 9:12
The IDE you choose has nothing to do with the code, you can use any project in any IDE. – sevenseacat Jan 13 '13 at 12:40
@sevenseacat: no, there is a thing called Java EE web project (in eclipse, it's called Dynamic Web Project). It will integrate with apache tomcat or other supported application server and you can deploy and run/debug directly from eclipse or netbeans. – suud Jan 13 '13 at 13:47
If you use maven you can run an eclipse:eclipse on the project and it will set it up for you. Netbeans and Eclipse are almost interchangeable. Deploying to tomcat/jetty,etc.. and running it from the IDE can be done with ease too. – Deco Jan 13 '13 at 22:39

Whether one IDE is more lightweight than another is pretty subjective. Do you have the identical features running etc? Even then it's not a like for like comparison. Couple of workarounds:

  1. The two IDEs both feature importers that will allow you to bounce projects back an forth - most of my projects run in all three major IDEs.

  2. You can performance tune your IDE, take a look at what Java heap settings they both start with and run a quick GC analysis on them when you do project work. You've be amazed what a few command line parameter changes can do.

  3. Good hardware is comparatively cheap. SSD Drive + 8 GB of RAM should see almost any IDE happy.

+1 for SSD and suitable amount of RAM. Both are terrific investments for a programer. – Matěj Zábský Jan 13 '13 at 10:40
Three major IDEs being? I can only think of Eclipse and Netbeans. – Florian Margaine Jan 13 '13 at 11:00
I'd guess IntelliJ? – scrwtp Jan 13 '13 at 11:07
I usually open around 60 tabs in eclipse. At minimum I expect there is no lag when typing in the IDE editor, switching tab, or showing dialog/window in the IDE. Currently I use company laptop, so SSD and RAM upgrade are not options, although that sounds a really good idea if I have my own laptop for works. – suud Jan 13 '13 at 11:46
IntelliJ was the 3rd major IDE :-) – Martijn Verburg Jan 13 '13 at 19:13
