  2. Java collections framework - Wikipedia

    en.wikipedia.org/wiki/Java_collections_framework

    java.util.Collection class and interface hierarchy Java's java.util.Map class and interface hierarchy. The Java collections framework is a set of classes and interfaces that implement commonly reusable collection data structures. [1] Although referred to as a framework, it works in a manner of a library. The collections framework provides both ...

  3. Java ConcurrentMap - Wikipedia

    en.wikipedia.org/wiki/Java_ConcurrentMap

    For ordered access as defined by the java.util.NavigableMap interface, java.util.concurrent.ConcurrentSkipListMap was added in Java 1.6, [1] and implements java.util.concurrent.ConcurrentMap and also java.util.concurrent.ConcurrentNavigableMap. It is a Skip list which uses Lock-free techniques to make a tree. Performance is O(log(n)).

  4. Generics in Java - Wikipedia

    en.wikipedia.org/wiki/Generics_in_Java

    Java only enforces type information at compile-time. After the type information is verified at compile-time, the type information is discarded, and at run-time, the type information will not be available. [6] Examples of non-reifiable types include List<T> and List<String>, where T is a generic formal parameter. [6]

  5. Observer pattern - Wikipedia

    en.wikipedia.org/wiki/Observer_pattern

    While the library classes java.util.Observer and java.util.Observable exist, they have been deprecated in Java 9 because the model implemented was quite limited. Below is an example written in Java that takes keyboard input and handles each input line as an event.

  6. Java concurrency - Wikipedia

    en.wikipedia.org/wiki/Java_concurrency

    Since JDK 1.2, Java has included a standard set of collection classes, the Java collections framework Doug Lea , who also participated in the Java collections framework implementation, developed a concurrency package , comprising several concurrency primitives and a large battery of collection-related classes.

  7. Iterator - Wikipedia

    en.wikipedia.org/wiki/Iterator

    For example, the iterator method is supposed to return an Iterator object, and the pull-one method is supposed to produce and return the next value if possible, or return the sentinel value IterationEnd if no more values could be produced. The following example shows an equivalent iteration over a collection using explicit iterators:

  8. Primitive wrapper class in Java - Wikipedia

    en.wikipedia.org/.../Primitive_wrapper_class_in_Java

    With Java 5.0, additional wrapper classes were introduced in the java.util.concurrent.atomic package. These classes are mutable and cannot be used as a replacement for the regular wrapper classes. Instead, they provide atomic operations for addition, increment and assignment. The atomic wrapper classes and their corresponding types are:
