In the autocomplete for methods, eclipse just says arg0, arg1 and so on. It does not show the name of the arguments. This isnot very helpful, as I'm having to remember the order of arguments especially when a method has more than 3/4 args.

How do I make eclipse display the name of each argument also in auto-complete?

There are several potential reasons, but the first you should check is whether in the Preferences/Java/Installed JREs the default is a JDK, not just a JRE. (Eclipse needs the source code to know parameter names, and JREs are not shipped with source code.)
