ABSTRACT

Back in chapter 7 we talked about the most basic sequence collections in Scala, the Array and the List. Since then we have seen other similar types. These collections share a large number of different methods that we have used to great effect. The sequences are not the only type of collection though. The Scala collections library is far more extensive than what we have seen so far. In this chapter we will examine the inheritance hierarchy of the entire collections library and look at three other types of collections in detail.
