Java technology overview
Java technology is both a programming language and a platform. The Java programming language is a high-level, object-oriented, concurrent, robust, secure language. It was developed by James Gosling at Sun Microsystems in 1991.
One of the most significant advantages of the Java platform is that it enables developers to write computer programs in one language and run those programs on many different types of computers. The use of Java technology simplifies the development and deployment of high-performance applications and services because programmers can write one set of code (the “write once, run anywhere” code) that runs on almost any type of computer without having to recompile or rewrite parts of the code for each type of computer on which it will run.
In addition to enabling programmers to write programs that can be executed on multiple types of systems, the Java platform provides a comprehensive set of tools for developers and system administrators, extensive documentation, and tutorials.

Why is Java technology important?
Java technology’s Write Once, Run Anywhere™ (WORA) principle makes it possible to run the same application or program on nearly any type of system or device, whether it’s a desktop computer, a server, a laptop, a smartphone, a tablet, smart TV, or an embedded system.
Java technology and the enterprise
Java technology is both a programming language and a platform. The Java programming language is a high-level, object-oriented language that has a particular syntax and style. A platform is a collection of technologies that are used as a base upon which other applications, tools, or programs are built.
Java technology’s versatility, efficiency, portability, and security make it the ideal technology for developing and deploying mission-critical applications. Its scalability allows organizations to develop and deploy mission-critical applications on an enterprise scale. In addition, because Java technology is platform independent, organizations can deploy these applications on any platform, includingWindows, Linux, and Mac OS X.
finally, Java technology’s security features make it an ideal choice for developing and deploying sensitive applications. Java technology’s security features include data encryption, user authentication, and access control.
Java technology and the Internet of Things
Java technology is both a programming language and a platform. The Java programming language is a high-level, object-oriented, concurrent, robust, secured and general-purpose programming language. It was originally developed by Sun Microsystems (which has since been acquired by Oracle Corporation) and released in 1995 as a core component of Sun’s Java platform. The language derives much of its syntax from C and C++ but has a simpler object model and fewer low-level facilities. Java applications are typically compiled to bytecode (class file) that can run on any Java Virtual Machine (JVM) regardless of computer architecture.
The Java platform is a suite of programs that facilitate developing and running programs written in the Java programming language. A platform has hardware, an operating system, and supporting software components. The Java platform differs from most other platforms in that it’s a software-only platform that runs on top of real hardware, making it versatile and portable. Oracle’s JDK 8 delivers enhanced developer productivity and performance for today’s applications with smaller footprints across all CPU architectures.
Java technology is part of the Internet of Things,— everyday devices that are connected to the Internet so they can be controlled remotely or share data—such as home appliances, cars, medical devices, industrial machines, RFID tags and smart utility meters. Oracle’s IoT solutions enable enterprises to build high-scale applications quickly using ready-made components while maintaining security and privacy.
Java technology and cloud computing
Java technology is both a programming language and a platform. The Java programming language is a high-level, object-oriented language that has a particular syntax and style. A platform is the hardware or software environment in which a program runs. We use the phrase “Java platform” to refer to the combination of the Java virtual machine (VM) and the Java application programming interface (API), which provides the functionality of a computing system.
The Java VM is a software layer that sits between programs and the hardware, providing portability and security. The Java API is a large collection of ready-made software components that provide many useful capabilities, such as graphical user interface (GUI) widgets. The API is grouped into libraries of related components called packages.
Cloud computing is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services). This technology allows organizations to rapidly provision resources when needed and release them when they are no longer needed, resulting in optimized resource utilization. Cloud computing uses virtualization technologies to provide scalable resources on demand through self-service portals.
Java technology’s versatility, efficiency, platform portability, and security make it the ideal technology for network computing from devices to datacenters to mobile smartphones.
Java technology and security
Java technology is both a programming language and a platform for application development. It is the underlying technology that differentiates state-of-the-art applications from traditional, static HTML pages.
Java technology provides a comprehensive, object-oriented environment for developing, deploying, and accessing enterprise-wide applications, portlets, and Web services. Built on open standards such as XML and SOAP, Java technologies offer developers a versatile, secure platform to build powerful applications and services.
The Java programming language is simple, object oriented, distributed, interpreted, robust, secure, architecture neutral, portable, high performance, multithreaded, and dynamic. It is the industry standard for developing mission-critical applications.
Java technology’s cross platform capabilities make it ideal for network computing. Three billion devices worldwide rely on Java technology including: desktop computers (Windows 95/98/NT/2000/XP), handheld devices (PDAs), routers (Cisco systems), printers (HP), medical devices (SunTime), credit card terminals (VeriFone), security systems (Nortel), automotive telematics systems (Volkswagen), game consoles (Nintendo 64) and many others.
Java technology and big data
Java technology is more than just a programming language. It’s a complete computer systems platform. Its defining characteristic is that it enables developers to “write once, run anywhere.” This means that a Java program can run on any computer system, as long as that system has a Java runtime environment installed.
This is made possible by the fact that the Java runtime environment is available for most major operating systems, including Windows, Linux, and Mac OS. It’s also available for popular web browsers, such as Firefox, Safari, and Chrome. In addition, many devices now have Java runtime environments installed, including smartphones, tablets, Blu-ray players, and more.
One of the biggest advantages of using Java technology is that it enables developers to create software on one platform and then deploy it on virtually any other platform with little or no modification. This “Write Once Run Anywhere” (WORA) capability makes Java technology ideal for developing cross-platform applications.
In addition to its portability, Java technology also offers several other advantages, including:
* Security: Java technology enables developers to create virus-resistant systems.
* Reliability: With Java technology, developers can be confident that their code will run on any compliant system without having to test it on each individual target platform.
* scalability: With its low memory footprint and support for multicore processors, Java technology helps enable developers to create scalable applications.
Java technology’s versatility and portability make it an ideal choice for developing big data solutions. given the vast amounts of data being generated by individuals and organizations all over the world every day
Java technology and artificial intelligence
Java technology is both a programming language and a platform. The Java programming language is a high-level, object-oriented language that has a particular syntax and style. A platform is the environment in which a program runs. The Java platform is a suite of programs that help you develop and run programs written in the Java programming language. The Java platform consists of the Java Runtime Environment (JRE), the Java Virtual Machine (JVM), and the Java Application Programming Interface (API).
The JRE provides the environment in whichJava bytecode (the compiled form of aJava program) can be executed. The JVM is the program that actually executes the bytecode. The API comprises a large collection of ready-made software components that provide many useful capabilities, such as graphical user interface (GUI) widgets. When you write applications you need not write all the code yourself; instead, you can make use of existing components fromthe API.
Artificial intelligence (AI) is an area of computer science and engineering focused on creating intelligent agents, which are systems that can reason, learn, and act autonomously. AI research deals with machines that can perform tasks that ordinarily require human intelligence, such as understanding natural language and recognizing objects.
The integration of AI technology with Java technology provides many benefits for developers, including:
-Ease of development: AI technologies written in theJava programming language are easier to develop than those written in other languages because the syntax is simpler and more consistent. In addition, the large number of existing components in the API lets you develop applications quickly by reusing existing code rather than having to write everything from scratch.
-Platform independence: Programs written in theJava programming language can run on any processor architecture as long as there is a JRE available for that architecture. This means that your programs will run unchanged on any hardware platform or operating system for which there is a JRE, making your programs much more portable than those written in other languages.
-Security: The Java programminglanguage was designed with security in mind, so it includes features that make it difficult for malicious code to exploit vulnerabilities in your programs. In addition, the JRE contains a built-in security manager that enforces security policies to further protect your programs from malicious code.
Java technology and the future of computing
Java technology is both a programming language and a platform for developing and deploying applications. Java technology’s versatility, efficiency, portability, and security make it the ideal technology for network computing. From laptops to datacenters, game consoles to scientific supercomputers, cell phones to the Internet, Java is everywhere!
The widespread adoption of the Java platform has made it one of the most important platforms for developers. Some of its key benefits include:
– Write Once, Run Anywhere (WORA): By compiling Java programs into platform-independent bytecode, WORA enables the same program to run on any Java-enabled device.
– Write Better Code: Thanks to strict compile-time checking and runtime checking, as well as support for sophisticated debugging features built into the Java language and platform, developers can avoid many common programming mistakes that can lead to bugs and crashes.
– Reuse & Extend Existing Code: The large and well-established base of reusable components makes it easy for developers to create sophisticated applications quickly and economically. In addition, developers can use the Java platform to create new components that can be integrated with existing code.
– Build Portable Apps: The Java platform is designed to be portable across different types of devices and operating systems. This means that developers can create applications that will run on any Java-enabled device without having to rewrite the code from scratch.
Looking to the future, the next version of the Java platform (Java SE 9) is currently in development and due for release in 2017. This release will include a number of new features and enhancements designed to make Java even more efficient and secure.
Java technology and you
Java technology is both a programming language and a platform.
The Java programming language is a high-level, object-oriented language that has a particular syntax and style. A programmer writes code in the Java programming language, then compiles that code into an executable form called a class file. A class file contains code that the Java virtual machine can understand. The Java virtual machine runs on top of another piece of software, typically an operating system, and provides a platform-independent environment in which to executing your code.
Why is this important? Code compiled into class files is not tied to any one platform—the same class files can run on any supported platform. This means that once you write a program in the Java programming language, you can run it anywhere without having to recompile it for each supported platform.
