Choosing the right IDE can make you or break you as a coder. Most developers would be lost without the comfort of their preferred IDE, which takes care of classpath, make files, command line arguments, etc. The problematic dependence on the IDE, while very beneficial, is off topic and a discussion for another post. We concentrate on 2 main platforms, Eclipse and Intellij Community Edition, comparing them, mainly in the Java SE context. Disclosure: Nadav uses Intellij on a regular basis, and Roi uses Eclipse.
