The Java platform also includes an extensive set of libraries.

#Java list code#

The Java Runtime Environment (JRE), complementing the JVM with a just-in-time (JIT) compiler, converts intermediate bytecode into native machine code on the fly. For example, the Java compiler, which converts Java source code into Java bytecode (an intermediate language for the JVM), is provided as part of the Java Development Kit (JDK). The Java platform consists of several programs, each of which provides a portion of its overall capabilities.

Jakarta EE (Enterprise Edition): Java SE plus various APIs which are useful for multi-tier client–server enterprise applications.

Java SE (Standard Edition): For general-purpose use on desktop PCs, servers and similar devices.

It is often used to develop applications for mobile devices, PDAs, TV set-top boxes, and printers.

Java ME (Micro Edition): Specifies several different sets of libraries (known as profiles) for devices with limited storage, display, and power capacities.

Java Card: A technology that allows small Java-based applications ( applets) to be run securely on smart cards and similar small-memory devices.

Different platforms target different classes of device and application domains: Java platforms have been implemented for a wide variety of hardware and operating systems with a view to enable Java programs to run identically on all of them. A Java platform includes an execution engine (called a virtual machine), a compiler and a set of libraries there may also be additional servers and alternative libraries that depend on the requirements. The Java platform is a suite of programs that facilitate developing and running programs written in the Java programming language. Oracle extended support for Java 6 ended in December 2018.

Oracle released the last free-for-commercial-use public update for the legacy Java 8 LTS in January 2019, and will continue to support Java 8 with public updates for personal use indefinitely.

Since Java 9 (and 10, 12, 13, 14, 15 and 16) is no longer supported, Oracle advises its users to "immediately transition" to a supported version. Oracle (and others) "highly recommend that you uninstall older versions of Java" than Java 8, because of serious risks due to unresolved security issues. Java 11, a currently supported long-term support (LTS) version, released on September 25, 2018. Regarding Oracle, it distributes Java 8, and also makes available e.g. Distributions include Amazon Corretto, Zulu, AdoptOpenJDK, and Liberica. As an open source platform, Java has many distributors, including Amazon, IBM, Azul Systems, and AdoptOpenJDK. The latest version is Java 17, released in September 2021.

On November 13, 2006, Sun Microsystems made the bulk of its implementation of Java available under the GNU General Public License (GPL). Memory management is handled through integrated automatic garbage collection performed by the JVM. all currently supported by Oracle, may use escape analysis optimization to allocate on the stack instead) and all variables of object types are references.

Java eschews certain low-level constructs such as pointers and has a very simple memory model where objects are allocated on the heap (while some implementations e.g. Java syntax borrows heavily from C and C++, but object-oriented features are modeled after Smalltalk and Objective-C. In addition, several languages have been designed to run natively on the JVM, including Clojure, Groovy, and Scala. Writing in the Java programming language is the primary way to produce code that will be deployed as byte code in a Java virtual machine (JVM) byte code compilers are also available for other languages, including Ada, JavaScript, Python, and Ruby. Java applets, which are less common than standalone Java applications, were commonly run in secure, sandboxed environments to provide many features of native applications through being embedded in HTML pages. Java is used in a wide variety of computing platforms from embedded devices and mobile phones to enterprise servers and supercomputers.

Java is a set of computer software and specifications developed by James Gosling at Sun Microsystems, which was later acquired by the Oracle Corporation, that provides a system for developing application software and deploying it in a cross-platform computing environment.
