Best Java IDE

NetBeans and Eclipse                                                        NetBeans &Eclipse are certainly the two best free IDEs for Java. NetBeans is still slightly more Java-centric, even though it has been adding features for other languages lately. Eclipse has been doing this for years.                   I like the GUI editor that ships built in to NetBeans (Eclipse has one available as  a  plug-in), but other than that the two have a very similar feature set for Java development.
