    Java Development Services FAQ

    What is Java development?

    Java is a general-purpose, competitive, class-based, and object-oriented programming language that emerged in 1995. Even though many more languages have appeared since then, Java remains one of the most popular languages, and the demand for java application development is only rising. The key features of Java are its simplicity and that it was meant to have as few implementation dependencies as possible. Java is being continuously upgraded via new versions, and its security and performance levels are steadily enhanced. Java powers numerous digital platforms and applications. Many of the emerging innovative products choose Java because it is considered to be one of the most reliable solutions.

    What are Java platform components?

    The process of translating the source code written in Java into the machine-readable and executable form happens within the so-called Java platform components. JDK is the abbreviation for Java Development Kit and stands for the Java development environment used for creating Java apps. It contains all needed tools for the development in Java. To run Java programs you need another component: a JRE or Java Runtime Environment that contains supporting files, and the JVM. With the help of the engine Java Virtual Machine, Java code is translated into the machine language, and the run speed of the application increases. 

    How is Java used in web development?

    Web development process with Java presupposes myriad ways, approaches and tracks. Three main and the most common are:  Java Servlet, JavaServer Faces, Java Frameworks. Java Servlet is a basic API (Application Programming Interface) that helps developers build applications for web browsers. The second approach is to use  JSF (JavaServer Faces). This is a more complex API that offers  more tools, but nevertheless has less options for customization than the Servlet. There are also plenty of Java frameworks (ready-made templates or code snippets) that help engineers to create code for common tasks in an easier way. Using this approach programmers can copy-and-paste already existing pieces of code.

    Is Java still good for web development in 2022?

    Thanks to its reliability, flexibility, simplicity, and access to versatile development options Java apps development is not losing its popularity. The tendency for the future is that Java will remain an excellent choice for many new businesses. Java is flexible, cross-platform, and allows seamless scaling. It is adapted for the cloud and offers a wide range of capabilities for microservices development. Most promising advanced tech solutions such as Big Data, ML, analytics, and chatbots widely use Java. Many companies that do not have in-house Java expertise opt for Java software development outsourcing and turn to Java app development companies for assistance. 

    Why You Need Java After All

    Reduced Time-to-Market

    Java has a well-designed reach API with a large ecosystem of well-tested libraries and frameworks for any use case. It is both easy and convenient to design, implement and deploy your applications in Java.

    Distributed Computing

    Java is designed as a distributed language and allows you to have several computers working simultaneously on one network. On top of that, Java has the whole ecosystem of Big Data processing frameworks like Hadoop, Spark, Sockets, Remote Method Invocation (RMI), Multicast Sockets, Kafka, and Message Passing Interface (MPI).

    Platform Independence

    Java allows running the same application on different systems – an indispensable point for a modern software solution. In fact, Java succeeds at this point as it is independent on both levels – source and binary.

    Multithreading Benefits
