  2. Java collections framework - Wikipedia

    en.wikipedia.org/wiki/Java_collections_framework

    Collection implementations in pre-JDK 1.2 versions of the Java platform included few data structure classes, but did not contain a collections framework. [4] The standard methods for grouping Java objects were via the array, the Vector, and the Hashtable classes, which unfortunately were not easy to extend, and did not implement a standard member interface.

  3. Collection (abstract data type) - Wikipedia

    en.wikipedia.org/wiki/Collection_(abstract_data...

    In computer programming, a collection is an abstract data type that is a grouping of items that can be used in a polymorphic way. Often, the items are of the same data type such as int or string . Sometimes the items derive from a common type; even deriving from the most general type of a programming language such as object or variant .

  4. Object-PL/SQL - Wikipedia

    en.wikipedia.org/wiki/Object-PL/SQL

    PL/SQL is available in Oracle Database (since version 7), TimesTen in-memory database (since version 11.2.1), and IBM Db2 (since version 9.7). O-PL/SQL allows the definition of classes and instantiating these as objects, thus creating user-defined datatypes as writing constructors, beyond using Java in stored procedures and triggers. Examples ...

  5. Java Database Connectivity - Wikipedia

    en.wikipedia.org/wiki/Java_Database_Connectivity

    An example of this is the KPRB (Kernel Program Bundled) driver [16] supplied with Oracle RDBMS. "jdbc:default:connection" offers a relatively standard way of making such a connection (at least the Oracle database and Apache Derby support it). However, in the case of an internal JDBC driver, the JDBC client actually runs as part of the database ...

  6. PL/SQL - Wikipedia

    en.wikipedia.org/wiki/PL/SQL

    Oracle Corporation usually extends PL/SQL functionality with each successive release of the Oracle Database. PL/SQL includes procedural language elements such as conditions and loops, and can handle exceptions (run-time errors). It allows the declaration of constants and variables, procedures, functions, packages, types and variables of those ...

  7. Java ConcurrentMap - Wikipedia

    en.wikipedia.org/wiki/Java_ConcurrentMap

    This example could be implemented with the Java 8 merge() but it shows the overall lock-free pattern, which is more general. This example is not related to the internals of the ConcurrentMap but to the client code's use of the ConcurrentMap. For example, if we want to multiply a value in the Map by a constant C atomically:

  8. SQLJ - Wikipedia

    en.wikipedia.org/wiki/SQLJ

    SQLJ is a working title for efforts to combine Java and SQL. It was a common effort started around 1997 by engineers from IBM, Oracle, Compaq, Informix, Sybase, Cloudscape and Sun Microsystems. It consists of the three parts: 0, 1 and 2. Part 0 describes the embedding of SQL statements into Java programs.

  9. List of Java APIs - Wikipedia

    en.wikipedia.org/wiki/List_of_Java_APIs

    The official core Java API, contained in the Android (Google), SE (OpenJDK and Oracle), MicroEJ. These packages (java.* packages) are the core Java language packages, meaning that programmers using the Java language had to use them in order to make any worthwhile use of the Java language. Optional APIs that can be downloaded separately.
