All of the coding languages I've ever used have only required me to use either the Visual Studio (VS) dev environment (both the classic version and the .net version) and my other favorite, UltraEdit, but that's mainly just an advanced text editor with syntax highlighting - it doesn't do any compiling. I use that for PHP coding since VS doesn't do PHP natively. I have toyed around with Eclipse while making some Nullsoft (NSIS) installers, but that was a long time ago, and if you've been coding in it for Java, by now you probably know your way around it more than me.

So for Java I don't really have any IDE's I can recommend from experience, but the current VS IDE also supports J#, which is a .Net version of Java, so I'm thinking alot of the syntax would be very similar, kind of like how C# is the .Net version of C++. Depending on how much of a timeframe you have before your deadline, you could try creating the quiz in J#, since coding a quiz would be extremely easy to do, it'd also be a good practice intro into using .Net and VS for ya, since imo (and thousands, if not tens of thousands of others) Visual Studio is the best IDE there is.
