Oracle Corporation, that provides a system for developing application software and deploying it in a cross platform computing environment.Java is used in a wide variety of computing platforms from embedded devices and mobile phones to enterprise servers and supercomputers.While they are less common than standalone Java applications, Java applets run in secure, sandboxed environments to provide many features of native applications and can be embedded in HTML pages.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, Java.Script, Python, and Ruby.In addition, several languages have been designed to run natively on the JVM, including Scala, Clojure and Apache Groovy.Java syntax borrows heavily from C and C, but object oriented features are modeled after Smalltalk and Objective C.Java eschews certain low level constructs such as pointers and has a very simple memory model where every object is allocated on the heap and all variables of object types are references.Memory management is handled through integrated automatic garbage collection performed by the JVM.On November 1. 3, 2.Sun Microsystems made the bulk of its implementation of Java available under the GNU General Public License GPL.The latest version is Java 9, the second of the two supported with e.Oracle and others has announced that using older versions other than Java 8 of their JVM implementation presents serious risks, due to unresolved security issues.PlatformeditThe Java platform is a suite of programs that facilitate developing and running programs written in the Java programming language.A Java platform will include 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.Java is not specific to any processor or operating system as 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.Different platforms target different classes of device and application domains Java Card A technology that allows small Java based applications applets to be run securely on smart cards and similar small memory devices.Java ME Micro Edition Specifies several different sets of libraries known as profiles for devices with limited storage, display, and power capacities.It is often used to develop applications for mobile devices, PDAs, TV set top boxes, and printers.Java SE Standard Edition For general purpose use on desktop PCs, servers and similar devices.Java EE Enterprise Edition Java SE plus various APIs which are useful for multi tierclientserverenterprise applications.The Java platform consists of several programs, each of which provides a portion of its overall capabilities.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 Runtime Environment JRE, complementing the JVM with a just in time JIT compiler, converts intermediate bytecode into native machine code on the fly.The Java platform also includes an extensive set of libraries.The essential components in the platform are the Java language compiler, the libraries, and the runtime environment in which Java intermediate bytecode executes according to the rules laid out in the virtual machine specification.Java Virtual MachineeditThe heart of the Java platform is the concept of a virtual machine that executes Java bytecode programs.This bytecode is the same no matter what hardware or operating system the program is running under.There is a JIT Just In Time compiler within the Java Virtual Machine, or JVM.The JIT compiler translates the Java bytecode into native processor instructions at run time and caches the native code in memory during execution.The use of bytecode as an intermediate language permits Java programs to run on any platform that has a virtual machine available.The use of a JIT compiler means that Java applications, after a short delay during loading and once they have warmed up by being all or mostly JIT compiled, tend to run about as fast as native programs.Since JRE version 1.Suns JVM implementation has included a just in time compiler instead of an interpreter.Although Java programs are cross platform or platform independent, the code of the Java Virtual Machines JVM that execute these programs is not.Every supported operating platform has its own JVM.Class librarieseditIn most modern operating systems OSs, a large body of reusable code is provided to simplify the programmers job.This code is typically provided as a set of dynamically loadable libraries that applications can call at runtime.Because the Java platform is not dependent on any specific operating system, applications cannot rely on any of the pre existing OS libraries.Instead, the Java platform provides a comprehensive set of its own standard class libraries containing many of the same reusable functions commonly found in modern operating systems.Most of the system library is also written in Java.For instance, the Swing library paints the user interface and handles the events itself, eliminating many subtle differences between how different platforms handle components.The Java class libraries serve three purposes within the Java platform.First, like other standard code libraries, the Java libraries provide the programmer a well known set of functions to perform common tasks, such as maintaining lists of items or performing complex string parsing.Second, the class libraries provide an abstract interface to tasks that would normally depend heavily on the hardware and operating system.Tasks such as network access and file access are often heavily intertwined with the distinctive implementations of each platform.The java. net and java.OS code, then provide a standard interface for the Java applications to perform those tasks.Finally, when some underlying platform does not support all of the features a Java application expects, the class libraries work to gracefully handle the absent components, either by emulation to provide a substitute, or at least by providing a consistent way to check for the presence of a specific feature.LanguageseditThe word Java, alone, usually refers to Java programming language that was designed for use with the Java platform.Programming languages are typically outside of the scope of the phrase platform, although the Java programming language was listed as a core part of the Java platform before Java 7.The language and runtime were therefore commonly considered a single unit.However, an effort was made with the Java 7 specification to more clearly treat the Java language and the Java virtual machine as separate entities, so that they are no longer considered a single unit.Third parties have produced many compilers or interpreters that target the JVM.Some of these are for existing languages, while others are for extensions to the Java language.These include Bean.Shell A lightweight scripting language for Java2.Clojure A dialect of the Lisp programming language.Groovy A dynamic language with features similar to those of Python, Ruby, Perl, and Smalltalk.JRuby A Ruby interpreter.Jython A Python interpreter.Kotlin An industrial programming language for JVM with full Java interoperability.Rhino A Java. Script interpreter.
