I don´t undestand this points in the FAQ about potential trips/trap in SCJP exam. I would like see an example code about it, can you help me?.
1 - Forward references to variables gives a compiler error.
2- All comparisons involving NaN and a non-NaN always result in false.
3- You can never cast objects of sibling classes (sharing the same parent).
