Get element from Set
scala
Solution
`Set` is not an ordered collection - you can't get element by index.
You could use `head` method to get single element from `Set` (it's not the first element, just some element).
You could also process all elements using `foreach` method:
for (s <- Set("a", "b")) println(s)
If you want to get all elements in some order you should convert `Set` to `Seq` using `toSeq` method like this:
val mySeq = mySet.toSeq
Problem
How can I get element at position in Set ? For a List can do : ``` val s : Set[(String, String)] = Set( ("a","b") ) val l1 = l(0) ``` But for Set : ``` val s : Set[(String, String)] = Set( ("a","b") ) val t1 = s(1) ``` I get compile time error : ``` Multiple markers at this line - type mismatch; found : Int(1) required: (String, String) - type mismatch; found : Int(1) required: (String, String) ``` Update : converting to List is an option but I though should be able to access a element at position in Set
