Java Fundamentals
The Java basics that trip people up early — == versus equals, immutable Strings, autoboxing, collections, inheritance and exceptions.
Twenty questions on the Java basics that decide whether the rest makes sense:

what a collection is actually good at, and where exceptions belong.
Aimed at students and developers in their first year. You get a score at the end, not a breakdown.
