Java Java on the Web. Java is a general purpose programming language with a number of features that make the language well suited for use on the World Wide Web. Small Java applications are called Java applets and can be downloaded from a Web server and run on your computer by a Java-compatible Web browser.

Java (software platform) Java is used in a wide variety of computing platforms from embedded devices and mobile phones to enterprise servers and supercomputers. While less common, Java applets run in secure, sandboxed environments to provide many features of native applications and can be embedded in HTML pages.

Java Development Kit (JDK) Definition - What does Java Development Kit (JDK) mean? The Java Development Kit (JDK) is a software development environment used for developing Java applications and applets. It includes the Java Runtime Environment (JRE), an interpreter/loader (java), a compiler (javac), an archiver (jar), a documentation generator (javadoc) and other tools needed in Java development.

Computer Software Definition Computer Software Definition. Software is a generic term for organized collections of computer data and instructions, often broken into two major categories: system software that provides the basic non-task-specific functions of the computer, and application software which is used by users to accomplish specific tasks.

Java virtual machine Overview of a Java virtual machine (JVM) architecture based on The Java Virtual Machine Specification Java SE 7 Edition. A Java virtual machine (JVM) is an abstract computing machine that enables a computer to run a Java program. There are three notions of the JVM: specification, implementation, and instance. The specification is a document that formally describes what is required of a JVM implementation.

- Java API. Java API is not but a set of classes and interfaces that comes with the JDK. Java API is actually a huge collection of library routines that performs basic programming tasks such as looping, displaying GUI form etc. In the Java API classes and interfaces are packaged in packages. All these classes are written in Java programming language and runs on the JVM. Java classes are platform independent but JVM is not platform independent.

- The code is then run on a virtual machine (VM), a program written in native code on the host hardware that interprets and executes generic Java bytecode. Further, standardized libraries are provided to allow access to features of the host machines (such as graphics, threading and networking) in unified ways.

Java (programming language) Java is a general-purpose computer programming language that is concurrent, class-based, object-oriented, and specifically designed to have as few implementation dependencies as possible.he method name  main  is not a keyword in the Java language. It is simply the name of the method the Java launcher calls to pass control to the program. Java classes that run in managed environments such as applets and Enterprise JavaBeans do not use or need a main() method.

What Are Objects in Java Programming? Object-oriented programming is a type of computer programming — such as Java — based on the premise that all programs are essentially computer-based simulations of real-world objects or abstract concepts. For example: Flight-simulator programs attempt to mimic the behavior of real airplanes.

Java Platform, Standard Edition Java Platform, Standard Edition or Java SE is a widely used platform for development and deployment of portable code for desktop and server environments. Java SE uses the object-oriented Java programming language. It is part of the Java software-platform family. Java SE defines a wide range of general-purpose APIs – such as Java APIs for the Java Class Library – and also includes the Java Language Specification and the Java Virtual Machine Specification.
