Scala Standard Library

A Scala Standard Library is standard library for a Scala language.

• Context:
  • It can (typically) contain:
    • scala.collection and its sub-packages contain Scala's collections framework
      • scala.collection.immutable - Immutable, sequential data-structures such as Vector, List, Range, HashMap or HashSet
      • scala.collection.mutable - Mutable, sequential data-structures such as ArrayBuffer, StringBuilder, HashMap or HashSet
      • scala.collection.concurrent - Mutable, concurrent data-structures such as TrieMap
    • scala.concurrent - Primitives for concurrent programming such as Futures and Promises.
    • scala.io - Input and output operations
    • scala.math - Basic math functions and additional numeric types like BigInt and BigDecimal
    • scala.sys - Interaction with other processes and the operating system
    • scala.util.matching - Regular expressions.
  • …
• Example(s):
  • Scala Standard Library, v2.13.5 [].
  • …
• See: Scala Concurrent Library.

Package structure

The scala package contains core types like Int, Float, Array or Option which are accessible in all Scala compilation units without explicit qualification or imports.

Notable packages include:

   scala.collection and its sub-packages contain Scala's collections framework
       scala.collection.immutable - Immutable, sequential data-structures such as Vector, List, Range, HashMap or HashSet
       scala.collection.mutable - Mutable, sequential data-structures such as ArrayBuffer, StringBuilder, HashMap or HashSet
       scala.collection.concurrent - Mutable, concurrent data-structures such as TrieMap
   scala.concurrent - Primitives for concurrent programming such as Futures and Promises
   scala.io - Input and output operations
   scala.math - Basic math functions and additional numeric types like BigInt and BigDecimal
   scala.sys - Interaction with other processes and the operating system
   scala.util.matching - Regular expressions

Other packages exist. See the complete list on the right.

Additional parts of the standard library are shipped as separate libraries. These include:

   scala.reflect - Scala's reflection API (scala-reflect.jar)
   scala.xml - XML parsing, manipulation, and serialization (scala-xml.jar)
   scala.collection.parallel - Parallel collections (scala-parallel-collections.jar)
   scala.util.parsing - Parser combinators (scala-parser-combinators.jar)
   scala.swing - A convenient wrapper around Java's GUI framework called Swing (scala-swing.jar)
