A Java virtual machine ( JVM) is a virtual machine that enables a computer to run Java programs as well as programs written in other languages that are also compiled to Java bytecode. The JVM is detailed by a specification that formally describes what is required in a JVM implementation. Having a specification ensures interoperability of Java ...
Swing is a GUI widget toolkit for Java. [ 1] It is part of Oracle 's Java Foundation Classes (JFC) – an API for providing a graphical user interface (GUI) for Java programs. Swing was developed to provide a more sophisticated set of GUI components than the earlier Abstract Window Toolkit (AWT). Swing provides a look and feel that emulates the ...
Java compiler. A Java compiler is a compiler for the Java programming language. Some Java compilers output optimized machine code for a particular hardware/ operating system combination, called a domain specific computer system. An example would be the now discontinued GNU Compiler for Java. [ 1]
A programming paradigm is a relatively high-level way to conceptualize and structure the implementation of a computer program. A programming language can be classified as supporting one or more paradigms. [ 1] Paradigms are separated along and described by different dimensions of programming. Some paradigms are about implications of the ...
Java bytecode is used at runtime either interpreted by a JVM or compiled to machine code via just-in-time (JIT) compilation and run as a native application. As Java bytecode is designed for a cross-platform compatibility and security, a Java bytecode application tends to run consistently across various hardware and software configurations.
JavaScript. JavaScript ( / ˈdʒɑːvəskrɪpt / ), often abbreviated as JS, is a programming language and core technology of the Web, alongside HTML and CSS. 99% of websites use JavaScript on the client side for webpage behavior. [ 10] Web browsers have a dedicated JavaScript engine that executes the client code.
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 (), [16] meaning that compiled Java code can run on all platforms that support Java without the need to recompile. [17]
Arrays are reified, meaning that an array object enforces its type information at run-time, whereas generics in Java are not reified. [6] More formally speaking, objects with generic type in Java are non-reifiable types. [6] A non-reifiable type is type whose representation at run-time has less information than its representation at compile ...
