Scala Seq is a trait to represent immutable sequences. This structure provides index based access and various utility methods to find elements, their occurences and subsequences. A Seq maintains the insertion order. Declaring Seq Variables The following is the syntax for declaring an Seq variable. Syntax val seq: Seq [Int] = Seq (1, 2, 3, 4, 5)
A great strength of the Scala collections classes is that they come with dozens of pre-built methods. The benefit of this is that you no longer need to write custom for loops every time you need to work on a collection. (If that’s not enough of a benefit, it also means that you no longer have to read custom for loops written by other developers.)
Outputs: a: Seq [Any] = List (1, 2, 3, (4,b)) res0: Seq [ (String, String)] = List ( (4,b)) So it will silently ignore those elements in the sequence which are not …

For instance, you might want to access an existing Java collection as if it were a Scala collection. Or you might want to pass one of Scala’s collections to a Java method that expects its Java counterpart. It is quite easy to do this, because Scala offers implicit conversions between all the major collection types in the JavaConverters object ...
