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 ...

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.)
