| Package | Description |
|---|---|
| java.util |
Contains the collections framework, legacy collection classes, event model, date and time facilities, internationalization, and miscellaneous utility classes (a string tokenizer, a random-number generator, and a bit array).
|
| java.util.concurrent.atomic |
A small toolkit of classes that support lock-free thread-safe programming on single variables.
|
| java.util.function |
Functional interfaces provide target types for lambda expressions and method references.
|
| java.util.stream |
Classes to support functional-style operations on streams of elements, such as map-reduce transformations on collections.
