Java API
There are two types of Java programming language application programming interfaces (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. The specification of these APIs are defined according to many different organizations in the world (Alljoyn, OSGi, Eclipse, JCP, E-S-R, etc.). The following is a partial list of application programming interfaces (APIs) for Java. APIs Following is a very incomplete list, as the number of APIs available for the Java platform is overwhelming. ; Rich client platforms * Eclipse Rich Client Platform (RCP) * NetBeans Platform ;Office_compliant libraries * Apache POI * JXL - for Microsoft Excel * JExcel - for Microsoft Excel ;Compression * ...

Java (programming Language)
Java is a high-level, class-based, object-oriented programming language that is designed to have as few implementation dependencies as possible. It is a general-purpose programming language intended to let programmers ''write once, run anywhere'' ( WORA), meaning that compiled Java code can run on all platforms that support Java without the need to recompile. Java applications are typically compiled to bytecode that can run on any Java virtual machine (JVM) regardless of the underlying computer architecture. The syntax of Java is similar to C and C++, but has fewer low-level facilities than either of them. The Java runtime provides dynamic capabilities (such as reflection and runtime code modification) that are typically not available in traditional compiled languages. , Java was one of the most popular programming languages in use according to GitHub, particularly for client–server web applications, with a reported 9 million developers. Java was originally de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Java 3D
Java 3D is a scene graph-based 3D application programming interface (API) for the Java platform. It runs on top of either OpenGL or Direct3D until version 1.6.0, which runs on top of Java OpenGL (JOGL). Since version 1.2, Java 3D has been developed under the Java Community Process. A Java 3D scene graph is a directed acyclic graph (DAG). Compared to other solutions, Java 3D is not only a wrapper around these graphics APIs, but an interface that encapsulates the graphics programming using a true object-oriented approach. Here a scene is constructed using a scene graph that is a representation of the objects that have to be shown. This scene graph is structured as a tree containing several elements that are necessary to display the objects. Additionally, Java 3D offers extensive spatialized sound support. Java 3D and its documentation are available for download separately. They are not part of the Java Development Kit (JDK). History Intel, Silicon Graphics, Apple, ...

XQuery API For Java
XQuery API for Java (XQJ) refers to the common Java API for the W3C XQuery 1.0 specification. The XQJ API enables Java programmers to execute XQuery against an XML data source (e.g. an XML database) while reducing or eliminating vendor lock in. The XQJ API provides Java developers with an interface to the XQuery Data Model. Its design is similar to the JDBC API which has a client/server feel and as such lends itself well to Server-based XML Databases and less well to client-side XQuery processors, although the " connection" part is a very minor part of the entire API. Users of the XQJ API can bind Java values to XQuery expressions, preventing code injection attacks. Also, multiple XQuery expressions can be executed as part of an atomic transaction. History and implementation The XQuery API for Java was developed at the Java Community Process as JSR 225. It had some big technology backers such as Oracle, [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jakarta XML RPC
Jakarta XML RPC (JAX-RPC; formerly Java API for XML Based RPC) allows a Jakarta EE application to invoke a Java-based web service with a known description while still being consistent with its WSDL description. JAX-RPC is one of the Java XML programming APIs. It can be seen as Java RMIs over web services. JAX-RPC 2.0 was renamed JAX-WS 2.0 ( Java API for XML Web Services). JAX-RPC 1 is deprecated with Java EE 6. The JAX-RPC service utilizes W3C (World Wide Web Consortium) standards like WSDL or Web Service Description Language. The core API classes are located in the Java package . * Supports web-based services and clients using RPC or remote procedure calls which are based on XML. * Allow for web service accessibility through Java APIs which in turn allows for communication between different Java applications. * Enables client communication with web service of different language and running on separate platform. It works as follows: #A Java program executes a method on a stub ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jakarta Server Faces
Jakarta Faces, formerly Jakarta Server Faces and JavaServer Faces (JSF) is a Java specification for building component-based user interfaces for web applications and was formalized as a standard through the Java Community Process being part of the Java Platform, Enterprise Edition. It is also an MVC web framework that simplifies the construction of user interfaces (UI) for server-based applications by using reusable UI components in a page. JSF 2.x uses Facelets as its default templating system. Users of the software may also choose to employ technologies such as XUL, or Java. JSF 1.x uses JavaServer Pages (JSP) as its default templating system. History In 2001, the original Java Specification Request (JSR) for the technology that ultimately became JavaServer Faces proposed developing a package with the name javax.servlet.ui In June 2001, '' JavaWorld'' would report on Amy Fowler's team's design of "the JavaServer Faces API" (also known as "Moonwalk") as "an application fra ...

Jakarta Messaging
The Jakarta Messaging API (formerly Java Message Service or JMS API) is a Java application programming interface (API) for message-oriented middleware. It provides generic messaging models, able to handle the producer–consumer problem, that can be used to facilitate the sending and receiving of messages between software systems. Jakarta Messaging is a part of Jakarta EE and was originally defined by a specification developed at Sun Microsystems before being guided by the Java Community Process. General idea of messaging Messaging is a form of ''loosely coupled'' distributed communication, where in this context the term 'communication' can be understood as an exchange of messages between software components. Message-oriented technologies attempt to relax ''tightly coupled'' communication (such as TCP network sockets, CORBA or RMI) by the introduction of an intermediary component. This approach allows software components to communicate with each other indirectly. Benefits of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jakarta Mail
Jakarta Mail (formerly JavaMail) is a Jakarta EE API used to send and receive email via SMTP, POP3 and IMAP. Jakarta Mail is built into the Java EE platform, but also provides an optional package for use in Java SE. The current version is 2.1.1, released on December 15, 2022. Another open source Jakarta Mail implementation exists - GNU JavaMail - while supporting only version 1.3 of JavaMail specification, it provides the only free NNTP backend, which makes it possible to use this technology to read and send news group articles. As of 2019, the software is known as Jakarta Mail, and is part of the ''Jakarta EE'' brand (formerly known as ''Java EE''). The reference implementation is part of the Eclipse Angus project https://projects.eclipse.org/projects/ee4j.angus Maven co-ordinates of the relevant projects required for operation are: * mail API: jakarta.mail:jakarta.mail-api:2.1.1 * mail implementation: org.eclipse.angus:angus-mail:2.0.1 * multimedia extensions: jakarta.ac ...

Java Package
A Java package organizes Java classes into namespaces, providing a unique namespace for each type it contains. Classes in the same package can access each other's package-private and protected members. In general, a package can contain the following kinds of types: classes, interfaces, enumerations, and annotation types. A package allows a developer to group classes (and interfaces) together. These classes will all be related in some way – they might all have to do with a specific application or perform a specific set of tasks. Programmers also typically use packages to organize classes belonging to the same category or providing similar functionality. Using packages In a Java source file, the package that this file's class or classes belong to is specified with the package keyword. This keyword is usually the first keyword in the source file. At most one package declaration can appear in a source file. package java.awt.event; To use a package's classes inside a Java sou ...

Acronym And Initialism
An acronym is a word or name formed from the initial components of a longer name or phrase. Acronyms are usually formed from the initial letters of words, as in '' NATO'' (''North Atlantic Treaty Organization''), but sometimes use syllables, as in '' Benelux'' (short for ''Belgium, the Netherlands, and Luxembourg''). They can also be a mixture, as in '' radar'' (''Radio Detection And Ranging''). Acronyms can be pronounced as words, like '' NASA'' and '' UNESCO''; as individual letters, like ''FBI'', '' TNT'', and ''ATM''; or as both letters and words, like ''JPEG'' (pronounced ') and ''IUPAC''. Some are not universally pronounced one way or the other and it depends on the speaker's preference or the context in which it is being used, such as '' SQL'' (either "sequel" or "ess-cue-el"). The broader sense of ''acronym''—the meaning of which includes terms pronounced as letters—is sometimes criticized, but it is the term's original meaning and is in common use. Dictionary ...

OpenGL
OpenGL (Open Graphics Library) is a cross-language, cross-platform application programming interface (API) for rendering 2D and 3D vector graphics. The API is typically used to interact with a graphics processing unit (GPU), to achieve hardware-accelerated rendering. Silicon Graphics, Inc. (SGI) began developing OpenGL in 1991 and released it on June 30, 1992; applications use it extensively in the fields of computer-aided design (CAD), virtual reality, scientific visualization, information visualization, flight simulation, and video games. Since 2006, OpenGL has been managed by the non-profit technology consortium Khronos Group. Design The OpenGL specification describes an abstract API for drawing 2D and 3D graphics. Although it is possible for the API to be implemented entirely in software, it is designed to be implemented mostly or entirely in hardware. The API is defined as a set of functions which may be called by the client program, alongside a set of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Adapter Pattern
In software engineering, the adapter pattern is a software design pattern (also known as Wrapper function, wrapper, an alternative naming shared with the decorator pattern) that allows the interface (computer science), interface of an existing class (computer science), class to be used as another interface. It is often used to make existing classes work with others without modifying their source code. An example is an adapter that converts the interface of a Document Object Model of an XML document into a tree structure that can be displayed. Overview The adapter design pattern is one of the twenty-three well-known Gang of Four (software), Gang of Four design patterns that describe how to solve recurring design problems to design flexible and reusable object-oriented software, that is, objects that are easier to implement, change, test, and reuse. The adapter design pattern solves problems like: * How can a class be reused that does not have an interface that a client requires? * ...
