What kind of problems is an Android beginner likely to encounter in using Scala?
I am a hobbyist programmer who makes and maintains one production system, largely coded in Python, which now has to be ported to Android. I don’t know Java at all. However, SL4A in Android makes Python a bit of a second class citizen re APIs, such as Google Cloud Messaging etc. However, for me, Java appears intimidating with its verbose syntax and strict typing. Scala’s syntax is more appealing and seems like a possible compromise.

Where is the iterator method .sliding() implemented
Forgive me if this is trivial, I’m just starting out.
scala.MatchError: null – why does pattern match fails?
Construct a function to return the default value of any type:
Collect with inline function
f(x) = x+2
p(y) = if(y>2) true else false
multiple pattern matching on iteration
val subjectpairs = IndexedSeq((8,0),(3,4),(0,9),(6,1)) val priors = subjectpairs.map { case( f,_) => f}.filter{ _ >0.0} val posts = subjectpairs.map { case( _,l) => l}.filter{ _ >0.0} This creates 2 sequences from the first , with the first and second members of tuples as non-zero respectively. However , this needs 2 iterations of the source sequence […]

nested case class generic filter method
I have some nested case classes that may look like the following:
