Java applet - Java applet A Java applet is an applet written in the Java programming language. They can run in a web browser, or in Sun's AppletViewer, a stand alone tool to test applets. Applets are used to provide interactive features to web applications that can not be provided by HTML. They are executed in a sandbox by most web browsers, preventing them to access local data. The code of the applet is downloaded from a web server and the browser either embeds the applet into a web page or opens a new window showing the applet's user interface. Since Java's bytecode is platform independent, Java applets can be viewed by browsers for many platforms, including Windows, Unix, MacOS or Linux. For applets to be compliant with MS.

Java programming language - Java programming language The Java language is an object-oriented programming language created by James Gosling and other engineers at Sun Microsystems. It was developed in 1991, as part of the Green Project, and officially announced on May 23, 1995, at SunWorld; being released in November. Gosling and friends initially designed Java, which was called Oak at first (in honour of a tree outside Gosling's office), to replace C++ (although the feature set better resembles that of Objective C). More on the history of Java can be found in the article about the Java platform, which includes the language, the Java virtual machine, and the Java API. Sun controls the Java specification and holds a trademark on the Java name. Table of contents showTocToggle("show","hide") 1 Overview 1.1.
Java virtual machine - Java virtual machine The Java virtual machine or JVM is a virtual machine that runs Java byte code, the code produced by a Java compiler or compilers from other languages which produce this code. Programs written in Java are compiled into a standardized portable binary format, which typically comes in the form of files with the .class extension. A program may consist of many classes, in which case, every class will be in a different file. The first 4 bytes in hexadecimal of each class must be CA FE BA BE. Class files may be packaged together in a .jar file, with the exact same format as a .zip file, optionally with a few extra special files added. This binary is then interpreted at runtime by.
Java API - Java API The Java API is an extensive collection of library routines (written in the Java programming language or in native code) that perform basic tasks such as GUI display and manipulation, sorting and countless others. Sun has defined 3 platforms targeting different application environments and segmented many of its APIs so that they belong to one of the platforms. The platforms are: Java 2 Platform, Micro Edition - targeting envionments with limited resources Java 2 Platform, Standard Edition - targeting workstation environments Java 2 Platform, Enterprise Edition - targeting large distributed enterprise or internet environments. Some additional APIs not in the above platforms may be found here. Table of contents showTocToggle("show","hide") 1 Organization of the APIs 2 API Development 3 Comparisons with Other Languages 4.
Java coffee - Java coffee Java coffee is a coffee produced on the island of Java. The term "Java" is sometimes used to mean coffee in general, particularly high quality coffee. For example coffee houses sometimes have the word "Java" in their name. Since the late 1990s, they may be playing off the popular Java programming language..
Java platform - Java platform The Java platform is a software platform developed by Sun Microsystems. The Java platform has been specifically developed so that programs written for it will look and function approximately the same regardless of the device it is running on.

Java board game - Java board game Java board game is a German-style board game which provides the atmosphere of the island of Java on a hexagonal board. Players build the island and score by setting up palace festivals at opportune moments. When players run out of hexagons to build the island, the game is over and a final scoring phase takes place and a winner is declared. Wolfgang Kramer and Michael Kiesling codesigned the game and it was published simultaneously in Germany by Ravensburger and in the United States by Rio Grande Games in 2000. It won the Deutscher SpielePreis 9th place 2001 and the Games Magazine Best Advanced Strategy Game 2002..
Java Database Connectivity - Java Database Connectivity Java Database Connectivity, or JDBC, is an API for the Java programming language that defines how a client may access a database. It provides methods for querying and updating data in a database. JDBC is oriented towards relational databases. The Java 2 Platform, Standard Edition includes the JDBC API together with an ODBC implementation of the API enabling connections to any relational database that supports ODBC. This driver is native code and not Java. Table of contents showTocToggle("show","hide") 1 Types of Drivers 2 Overview of the API 3 Example 4 Additional Resources Types of Drivers There are commercial and free drivers available for most relational database servers. These drivers fall into one of the following types: Type 1 driver Type 2 driver Type.
Java Transaction API - Java Transaction API The Java Transaction API is one of the J2EE APIs allowing distributed transactions to be done across multiple XA resources. It provides for: demarcation of transaction boundaries X/Open XA API allowing resources to participate in transactions. Table of contents showTocToggle("show","hide") 1 X/Open XA architecture 2 JTA implementation of the X/Open XA Architecture 3 Examples 3.1 Transaction Management in a Simple Application 3.2 Transaction Management in an EJB 4 Additional Resources X/Open XA architecture In the X/Open XA architecture, a transaction manager or transaction processing monitor AKA TP monitor, coordinates the transactions across multiple resources such as a database. Each resource has its own manager. The resource manager typically has its own API for manipulating the resource, for example the JDBC API used by.
Java Naming and Directory Interface - Java Naming and Directory Interface The Java Naming and Directory Interface is an API for directory services. It allows clients to discover and lookup data and objects via a name and, like all java APIs, is independent of the actual implementation. Additionally, it specifies an service provider interface or SPI that allows directory service implementations to be plugged into the framework. The implementations may make use of a server, use a flat file or a database, the choice is up to the vendor. The JNDI API is used by the Java RMI and J2EE APIs to lookup objects in a network. JINI has its own lookup service and does not use the JNDI API. The API provides: a mechanism to bind an object to a name.
Java Message Service - Java Message Service The Java Message Service API is a Java Message Oriented Middleware API for sending messages between two or more clients. The API supports two models: publish/subscribe model point-to-point or queuing model The publish/subscribe model supports publishing messages to a particular message topic. Zero or more subscribers may register interest in receiving messages on a particular message topic. In this model, neither the publisher nor the subscriber know about each other. In the point-to-point or queuing model,a producer posts messages to a particular queue and a consumer reads messages from the queue. Here the producer knows the destination of the message and posts the message directly to the consumer's queue..
Java 2 Platform, Enterprise Edition - Java 2 Platform, Enterprise Edition Java 2 Platform, Enterprise Edition or J2EE is a Standard for developing distributed Multi-tier architecture applications, based on modular components. The standard uses several technologies, including JDBC and CORBA, and extends their functionality with Enterprise Java Beans, Java Servlets, Java Server Pages and XML technologies. This allows the developer to create an Enterprise Application that is portable between platforms and scalable, while integrating with several legacy technologies.

Java 2 Platform, Micro Edition - Java 2 Platform, Micro Edition Java 2 Platform, Micro Edition or J2ME is a collection of Java APIss targeting embedded consumer products such as PDAss, cell phones and other consumer appliances. J2ME has become a popular option for creating cell-phone games as they can be emulated on a PC during the development stage and automatically uploaded to the cell-phone. This contrasts with the difficulty of developing, testing, loading games for other special gaming platforms such as those made by Nintendo, Sony and others as special and expensive hardware and kits are required. Some cell-phone makers also extend the J2ME platform to provide more robust effects such as 3D grpahics and audio which lacks a specification in the current J2ME APIs. Configurations And Profiles J2ME devices implement.
Java 2 Platform, Standard Edition - Java 2 Platform, Standard Edition Java 2 Platform, Standard Edition or J2SE is a collection of java Application Programming Interfaces targeting Java platform applications running on a workstation. General APIs java.io Routines for normal input and output. This includes streams and filehandling. java.lang Contains classes thought applicable to most java programs. This package contains standard java types like Integers and Strings as well as basic exceptions, math functions, threading, security functions, as well as some information on the underlying native system. Classes in java.lang package are always available to the programmer, without needing a special import declaration at the beginning of a sourcecode file. java.lang.ref Special routines for interacting with the garbage collector. For example, one can create a weak reference, which allows one to refer.
JavaServer Pages - JavaServer Pages JSP or JavaServer Pages is a Java technology that allows developers to dynamically generate HTML, XML or some other type of web page. The technology allows java code and certain pre-defined actions to be embedded into static content. The JSP syntax adds additional XML tags, called JSP actions, to be used to invoke built-in functionally. Additionally, the technology allows for the creation of JSP tag libraries that act as extensions to the standard HTML or XML tags. Tag libraries provide a platform independent way of extending the capabilities of a web server. JSPs are compiled into Servlets by a JSP compiler. A JSP compiler may generate a servlet in java code that is then compiled by the java compiler, or it may generate byte code for the servlet directly..

Java remote method invocation - Java remote method invocation The Java Remote Method Invocation API, or RMI, is an application programming interface for performing remote procedural calls. There are two common implementations of the interface, the initial one to be implemented known as JRMP and a version compatible with CORBA. Usage of the term RMI may denote solely the programming interface or may signify both the API and JRMP, whereas the term 'RMI-IIOP, read RMI over I-OP, denotes the RMI interface over the CORBA IIOP bus. The original RMI API was generalized somewhat to support different implementations. Additionally, work was done to CORBA, adding a pass by value capability, to support the RMI interface. Still, the RMI-IIOP implementation supports only a subset of the JRMP implementation. RMI is currently being extended.
