Java is a popular choice in developing apps with extreme performance and scalability requirements. Technologies of Java help develop big, robust and high performance apps that could be easily extended.
Java is supported by all major platforms and Java programs written once could be executed anywhere and there’s no need for any vendor-centric deployment descriptions to port an app from server to server. Java programs, in a nutshell are also called as ‘write once, run anywhere’.
JAVA DEVELOPMENT COMPANY SERVICES
An ideal Java web development company has an expertise in the different Java technologies, including J2EE, J2SE, J2ME, JavaFX and database technologies such as MySQL and Oracle. Dedicated Java developers convert the objectives and ideas of clients into apps through offering exceptional Java/J2EE app development services that meet their expectations.
THE JAVA DEVELOPMENT KIT
The Java development kit or JDK is the implementation of either one of the Java Platform, Standard Edition, Enterprise Edition or Micro Edition platforms released by Oracle in the form of a binary product that is aimed for a Java developer on Linux, Solaris, Windows or MacOS. The JDK includes a private JVM and some other resources to finish the Java application development. Since the Java platform was introduced, it has by far been the most widely used software development kit around.
JRE VS JDK
The main download website of Java offers the JRE or the Java Runtime Environment. It includes the basic software that allows running Java applets and desktop apps on a computer. There is also the Java development kit, which is what is needed to develop Java apps. Some development-related software, including the Android software development kit also needs the JDK on the system. Also, the JDK include the JRE, so it only needs installing one of them.
People who are new to Java may be confused on whether to use the JRE or the JDK. To run Java apps and applets, JRE could be downloaded. Nevertheless, for developing Java applications and applets and run them as well, the JDK is needed. Developers of Java initially are presented with two JDK tools, namely, Java and Javac. Both are run from the command prompt. The Java source files are simple text files that are saved with Java extension. After writing and saving the Java source code, the Javac compiler is invoked to build .class files. As soon as the .class files are made, the ‘Java’ command could be used for running the Java program.
For developers who want to work in an IDE or integrated development environment, a JDK bundled with Netbeans could be downloaded from the website of Oracle. These IDEs hasten the process of development through introducing point-and-click and drag-and-drop features to create an app.
THE DIFFERENT JDKS
There are various Java development kits for different platforms. The supported platforms include Linux, Windows and Solaris. Users of Mac require a different software development kit that includes adaptations of some tools that are found in the JDK.
JAVA APPLICATIONS
With the growing relevance of web based and mobile base apps, Java nowadays is the foundation for most networked apps and considered to be useful in scripting, enterprise software, web-based content, games and mobile apps. Every organization uses Java in one way or the other. As per Oracle, there are more than three billion devices run apps that are designed on the development platform. Java is used in designing the following apps:
- Embedded systems
- Desktop GUI apps
- Web servers and app servers
- Web apps, such as eCommerce apps, front and back office electronic trading systems, data processing projects, settlement and confirmation system and more
- Mobile apps such as android apps
- Scientific apps
- Enterprise apps
- Middleware products
THE ADVANTAGES OF THE JAVA PROGRAMMING LANGUAGE
➢ Offers higher cross-functionality and portability as programs written in a platform could run across mobiles, desktops and embedded systems
➢ Java is a mature language, thus more predictable and stable. The Java Class Library allows cross-platform development
➢ Java is simple, free, object-oriented, distributed and supports multithreading and provides multimedia and network support
➢ Has a big active user community and available support
➢ Java programs are compiled independent of platform in bytecode language that allows the same program for running on any machine with JVM installed
➢ Has powerful development tools such as NetBeans and Eclipse SDK that have debugging capability and provide an integrated development environment.
➢ Relatively seamless forward compatibility from version to version
➢ Growing language diversity, evidenced by Java compatibility with Groovy, Scala, Clojure and JRuby.
Twenty years after its inception, Java is still able to deliver great value to the software development world. As a matter of fact, Java 8 offers new features like scalable and flexible platform for the IoT, new date and time library and API, less boilerplate code, integration with JavaScript, refreshed graphics toolkit and more. The upgrades are in line with modern enterprise requirements. The Java development kit allows the development or robust and highly scalable apps.
