What is Java?

Java, a programming language originally released in 1995 as a core component of Sun Microsystem. As the years went by it has evolved, capable of powering a large scale of today's digital world.  Java is known to have lesser implementation dependencies due to its class-based, and object-oriented programming language (OOPT) nature. This makes Java commonly used from enterprise applications and building dynamic digital products to technologies such as AR(augmented reality) and VR(virtual reality), big data.

Currently, Java is the top three programming language due to it being secure, fast, and reliable. In addition, Java is robust, dynamic, and scalable, as such the application built using it is capable of handling a huge amount of requests at once. Developers prefer using it as it produces much better results

1. Mobile applications

Java is the first choice when it comes to Android application development

This is so due to the feature named Java Micro Edition (J2ME), which provides a cross-platform framework to build mobile applications. In addition, Java works amazingly with Android Studio and Kotlin which are two technology development environments that developers are highly familiar with.


Popular applications developed using Java-based SDK (Software Development Kit) :

  • Netflix
  • Tinder
  • Spotify
  • Wikipedia Search
  • Google Earth
  • Uber


2 GUI Applications

Java provides multiple features that help in developing GUI applications for example:

  • Abstract Window Toolkit (AWT)
  • Swing API
  • Java Foundation Classes 
  • JavaFX


These features are what help developers develop tree-based applications and 3D graphical applications

Popular Java-based GUI applications:

  • Acrobat Reader
  • ThinkFree


3. Embedded Systems

Embedded are multiple systems that form a part of the larger electromechanical systems to perform a specific function. Java was originally intended to create embedded systems

As said before that Java is robust capable of handling application exceptions with great efficiency

Java-based embedded systems applications:

  • Nest Thermostat 
  • Voyager


4. Big Data technologies

Big data deals with a multitude of data sets by analyzing and systematically extracting information from it. Java provides capabilities to process huge amounts of data while deriving valuable insights from it using Java cloud development tools, libraries, and frameworks.

5. Scientific Applications

Java includes secure and robust features to help build applications for scientific computing. Java helps in this development by providing powerful mathematical calculation capability. 


6. Enterprise solutions

Java is one of the best choices for developing enterprise solutions due to its scalable and robust nature. Usually, Enterprise Java applications are very big as such developers utilize Java Enterprise Edition, which provides tools to create multi-thread large-scale applications.
