What is Java?

Discover Java, a versatile and powerful programming language. Unleash your potential to create robust applications.

Simply put, Java is a programming language used to develop software applications. As of 2019, it is the most popular in the world, mainly because it is open source and runs on all operating systems, following the “Write Once, Run Anywhere” logic.

Developed in 1995 by Sun Microsystems, it is very similar to C and C++, but easier to use and with advanced features. Today, Java is used to build robust, scalable, portable, and distributed end-to-end applications, from games and websites to client-server networks and Big Data technology.

What is a Java program made of?

A Java program is built on three main components: JDK, JVM and JRE.

JDK

Developers use Java Development Kits to write code and run it through a JRE. This includes a series of tools that interpret, compile, package, and archive all the data in the JDK.

JVM

A Java Virtual Machine translates all code written by the developer into Java bytecode. This way, any machine implements this code according to its operating system.

JRE

A Java Runtime Environment is the physical implementation or runtime instance of a JVM. It contains the JVM, libraries, packages, and support files used to run a program.

Types of applications developed with Java

As a Java development company, our software outsourcing services provide solutions for all types of businesses.

Applets

Also known as browser-based programs, applets are applications designed for the Internet. Their design allows them to reside on servers and run on any machine with a Java-compatible browser.

Web Applications

Every website ever created is based on a web application. Behind the scenes, Java communicates with the user's device and tells it exactly how to display all the information written in the code.

Distributed Applications

Java applications can also be divided into modules or components, which can run simultaneously on many different devices. These programs communicate and work with each other through distributed processing.

Standalone applications

Just like C++, Java can be used to design standalone applications. These programs run and store on independent devices. Data can also reside on a server, giving users access to synchronized data.

The benefits of Java

Java development offers diverse services for companies of all sizes.

  • Easy to use: Java makes coding easier by removing complexities seen in many other programming languages, such as operator and pointer overloading. It is designed to be a powerful, enhanced C++-based language that is simple to use and learn.
  • Full portability: Java programs run on any machine capable of installing a JRE – which is basically any machine. This feature, known as platform independence, allows source code to run on virtually any network, server, or client.
  • Network-centric: The Java ecosystem is optimized for easy access and management of resources across a network. In today's emerging network economy, client-server and multi-tier applications are bound to grow.
  • Reliability: Developers are human and humans make mistakes. Java was designed with this fact in mind, so it aims to reduce the chance of fatal errors through its object-oriented construction. All operations are performed using objects, making Java a robust platform for data manipulation.
  • Performance and security: The all-terrain Java architecture makes your programs and scripts faster, more efficient, and ready to test any code in a secure environment. More recent releases have focused on providing Java with robust code with reliable error and threat detection protocols.

What makes Java a high-level language?

Java allows programmers to write code in a language everyone is familiar with – plain English. Developers can use English-based commands to create computer instructions instead of writing numerical codes. This is why Java is considered a “high-level” language, as it is easily read and written by humans.

And just like English, Java has a set of rules known as “syntax” that determines how all instructions are written. When a program is ready to run, these high-level instructions are translated into numerical codes that computers can understand and execute.

Java development outsourcing

Harnessing the full potential of Java and its capabilities requires an experienced team of software developers with specific skills. Today, thousands of companies choose to partner with a Java development company to gain access to the best technology talent for their projects. The technological and industrial know-how of Java outsourcing companies guarantees higher quality products and shorter product launch times.

Software outsourcing companies remotely develop partial or complete software products according to customer requirements and project schedule. This translates into customized solutions that work for your specific business in your specific environment.

Software outsourcing companies guide their clients through the entire development process and adapt their work to perfectly fit each project.
