*/ public at scala.collection.mutable.AbstractMap.getOrElseUpdate(Map.scala:91) Could you please advise how to overcome the error? Reply. Valentin Nikotin.

Package structure . The scala package contains core types like Int, Float, Array or Option which are accessible in all Scala compilation units without explicit qualification or imports. As I understand, TrieMap.getOrElseUpdate is still not truly atomic, and this fixes only returned result (it could return different instances for different callers before this fix), so the updater function still might be called several times, as documentation (for 2.11.7) says: Note: This method will invoke op at most once. ms getOrElseUpdate (k, d) If key k is defined in map ms, return its associated value. Otherwise, update ms with the mapping k -> d and return d. Removals: ms -= k: Removes mapping with key k from ms as a side effect and returns ms itself.

Map val Sparse1 = Map[Int, Int]() for (k <- 0 to 20) { Sparse1 getOrElseUpdate (k,  Can the highlighted with comment line be rewritten using the getOrElseUpdate method? P.S. I am only at the 4th part of the "Scala for the impatient", so please don't teach me now about functional Scala which, I am sure, can be more beautiful here. Thanks. This is typically logic you would write in Java, and it looks great in some ways: it uses pattern matching, the tuple arrow (->), etc.But it turns out that Scala collections already provide the getOrElseUpdate method on mutable maps. Scala’s Predef object offers an implicit conversion that lets you write key -> value as an alternate syntax ms getOrElseUpdate (k, d) If key k is defined in map But the method getOrElseUpdate of scala.co The ScalaDoc states that a scala.collection.concurrent.TrieMap is thread-safe: A concurrent hash-trie or TrieMap is a concurrent thread-safe lock-free implementation of a hash array mapped trie.

The 'getOrElse(Default)' method goes into the Scala class hierarchy… Return optional values from a function with the Option class. Use None, isDefined , get and getOrElse.

outputs look fine, I noticed java13 wasn't listed on scala page, decided to look into scala PKGBUILD and found this : depends=('java-environment=8' 'java-runtime=8') Try switching to java8 as default.
