What is strictfp ? In what way is it related to float and double expressions ?

Howdy -- strictfp is a modifier that can be applied to a class or a method, and as far as the exam is concerned:
* If marking a method, it forces the method to be strictfp-compliant, which means it adheres to the IEEE 754 standard for floating point numbers, as opposed to using whatever precision the underlying platform can support (which could be *greater* but is always at least guaranteed by the Java spec to be IEEE 754 compliant).
* If marking a class, it means that all methods in that class are strictfp.
And then, of course, you also have to know the details of the IEEE 754 specification. But it is not that bad, really!
OK, just kidding about the spec -- you do NOT have to know anything more than what the strictfp modifier is for, and where it can be used (e.g. on a class or method, but not a variable, etc.)
Cheers,
Kathy

Salim, compile constant expressions (JLS 15.28) are also implicitly strictfp.
