2. 2020 marks the 25th anniversary of Java, one of the most widely used
programming languages across the globe. The language has been around
for more than two decades and is enjoying the sunshine of fame.
The TIOBE Programming Community Index depicts the popularity of the
language where it holds the first position. Looking back at the results,
Java has always been either on number 1 or number 2. Grounded in
readability and simplicity, Java has a long list of features that is making it
a popular language.

6. Desktop
Applications
06
Desktop GUI applications are easily built by
the Java developers using this amazing
programming platform.
APIs like AWT(Abstract Windowing Toolkit),
Swing, JavaFX help in building these GUI
applications.
Examples: Acrobat Reader, ThinkFree,
MediaPlayer

7. 07
Today, the majority of the phones and smart devices have Android OS.And the
best approach for building Android applications is to opt for Java
development.
Mobile Applications
Java ME or Micro Edition (Java ME or J2ME) is the framework used for building
mobile applications across various platforms on devices supporting Java.
Android is a more popular operating system in mobiles and other digital
devices. All Android apps are coded using the Android SDK that is similar to
JDK.
Examples: Netflix, Tinder, Google Earth, Uber

8. A web application is a client-server program that is delivered via a browser
interface. Java supports web-development applications with servlets, struts,
Java server pages, and Java Server Faces, etc.
Web Applications
One of the biggest perks for which Java is known is its scalability. Big
eCommerce websites like Amazon and Wayfair rely on Java in order to scale
their site whenever new products are being introduced.
Examples: Google Slides & Gmail

Embedded or integrated systems are computer systems that assemble to
perform dedicated functions for a larger system.
Embedded Systems
Multimedia in the car, mobile computing, wireless communication are few of
the embedded systems that you may have used unintentionally. These systems
are usually developed using Java.
Examples: SIM cards of smartphones run a variant of JVM for 20 years.

10. Distributed
Applications
10
With the help of Java programming, the distributed
application communicates with multiple servers on
the same network.
Remote method invocation and CORBA (Common
Object Request Broker Architecture) are APIs that
help in creating the distributive system.
Java Intelligent Networking Infrastructure helps it
to register and search distributed services as per
the requirements.

11. 11
According to Oracle, Java has managed to gain a lot of share (more than 90%)
of the enterprise computer system.
Enterprise Applications
ava understands the need for enterprises and for this reason it runs inside JVM.
Java Virtual Machine having security features verifies the bytecode received
from the external system while preventing security breaches.
Example: Naukri, Jabong, Flipkart. Trivago, ibibo, Spotify, etc.

12. Having a high level of portability, these applications are fast and secure. It
has powerful mathematical calculations that give the same result on
multiple platforms.
Scientific Applications
MATLAB is a renowned scientific application that takes help from Java for
developing frontend (interactive user-interface) and backend (the core of the
system).
Examples: Research, science, medical science, space, aeronautics.

13. 13
Java is a blue collar language and is part of almost every software
development project. It molds itself according to the business requirements.
Not just feature-rich, but you can build highly secure & scalable applications
with help of java developers having years of experience.
Wrapping Up
As long as Oracle continues to invest in developing better versions, Java is here
to stay and that too for the longest duration. As Java is a foundation for many
other programming language, it will continue to dominate.
