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:
Output is not giving as Range(1,2,3,4) for val from1Until5 = 1 until 5 println(s”Range from 1 until 5 where 5 is excluded = $from1Until5″)
