The Java virtual machine (JVM) loads the class files and either interprets the bytecode or just-in-time compiles it to machine code and then possibly optimizes it using dynamic compilation. A standard on how to interact with Java compilers was specified in JSR 199. See also. List of Java Compilers; javac, the standard Java compiler in Oracle's JDK
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 ), [16] meaning that compiled Java code can run on all platforms that support Java without the ...
Java annotation. In the Java computer programming language, an annotation is a form of syntactic metadata that can be added to Java source code. [1] Classes, methods, variables, parameters and Java packages may be annotated. Like Javadoc tags, Java annotations can be read from source files. Unlike Javadoc tags, Java annotations can also be ...
t. e. In computer science, ahead-of-time compilation ( AOT compilation) is the act of compiling an (often) higher-level programming language into an (often) lower-level language before execution of a program, usually at build-time, to reduce the amount of work needed to be performed at run time . Most often, it is associated with the act of ...
Program execution. In computing, a compiler is a computer program that translates computer code written in one programming language (the source language) into another language (the target language). The name "compiler" is primarily used for programs that translate source code from a high-level programming language to a low-level programming ...
Compiled language. A compiled language is a programming language for which source code is typically compiled; not interpreted . The term is vague since, in principle, any language can be compiled or interpreted and in practice some languages are both (in different environments). [1] In some environments, source code is first compiled (to an ...
Generics in Java. Generics are a facility of generic programming that were added to the Java programming language in 2004 within version J2SE 5.0. They were designed to extend Java's type system to allow "a type or method to operate on objects of various types while providing compile-time type safety". [1] The aspect compile-time type safety ...
v. t. e. Dynamic compilation is a process used by some programming language implementations to gain performance during program execution. Although the technique originated in Smalltalk, [1] the best-known language that uses this technique is Java. Since the machine code emitted by a dynamic compiler is constructed and optimized at program ...
