Package structure

The scala package contains core types.

scala.collection and its subpackages contain a collections framework with higher-order functions for manipulation. Both scala.collection.immutable and scala.collection.mutable data structures are available, with immutable as the default. The scala.collection.parallel collections provide automatic parallel operation.

Other important packages include:

Many other packages exist. See the complete list on the left.

Automatic imports

Identifiers in the scala package and the scala.Predef object are always in scope by default.

Some of these identifiers are type aliases provided as shortcuts to commonly used classes. For example, List is an alias for scala.collection.immutable.List.

Other aliases refer to classes provided by the underlying platform. For example, on the JVM, String is an alias for java.lang.String.
