Key features of Java programming language

  • Simplicity: Java offer easy user experience for developers as well end users. Java’s inbuilt design and librariesare its most significant advantage when compared with other similar object-oriented programming languages.
  • Portability: Java can be run anytime and anywhere in any hardware and software. Wide range of software and hardware are using Java.
  • Allocation: Features like stack provisioning, garbage collection and automatic memory distribution differentiate Java way apart from other programming language.
  • Distributive: Java is highly networking competent. Usually, Java receives and sends files informally.
  • Extremely secure: Java enforces strong security standards with safe programming.

Why Java will remain popular language in future?

Java has wider application, than most of its peer languages like Asp.Net, PhP, Python etc.  Its application includes widest range of tools and technologies, covering from mobile to web to wearable to space science. Here in this article, we have compiled list of most popular applications of Java, which will make it dominant language of future.

Java application in Big data

Java is a dominant programming language in Big data, along with Python. It is used in various frameworks for handling large scale data.

Apache Hadoop

Hadoop is Java-based programming framework which processes large datasets in a distributed computing environment. Hadoop runs in master slave architecture, where master controls the working of entire distributed computing stack. Hadoop has become very popular among companies in storing massive data and performing analysis.

Companies using Hadoop framework: IBM, Amazon web services, Intel etc

Apache Spark

Spark is another popular Java framework using in Big data. Spark is basically a cluster computing framework and can run on thousands of machines (distributed clusters). Spark is used in large ETL (extract, transform, and load) operation, predictive analytics, and reporting applications

Companies using Spark framework: Uber, Slack, Hubspot, Shopifyetc

Apache Mahout

Apache Mahout is Machine Learning library and big data tool, built using Java. It is used for performing machine learning functions like classifications, clustering and recommendations.

Companies using Apache Mahout:Adobe, Facebook, LinkedIn, Foursquare, Twitter, and Yahoo

Why Java is language of choice for IOT

According to Oracle, Java flexibility and being virtually universal is a key reason why most of IOT programmers use Java.

Java offers extensive library of APIs that can be easily applied in creating embedded applications make Java most suitable candidate for IOT programming. Transitions of platform during updates is much smoother and less error prone than other languages like C. Java has been part of embedded  device right from start when it was used in PDA and basic mobile phone. Its application in wearable technologies, TV, mobiles and other electronics devices has made it superior programming language for IOT.

Android Application

Java is ruling mobile application market through Android Application components, which hold share of more than 73% of all installed apps via Google play store. More than 450,000+ apps are using Android Java, including top apps like Youtube, Tiktok etc.

Java use in financial services

Chatbot development

Java is best tool for chatbot due to its features like portability, transparency, maintainability, debugging, visualization and so much more in mission critical projects.

According to Chatbotsjournal, Java is used by leading chatbots like IBM Watson Conversation Service, Api.ai, Pandorabots.

Fraud Detection and Management

Financial companies and banks are using AI tools for financial fraud and credit card fraud detection. Java is used to build these AI tools which generate unexpected insights, discover patterns and create predictive model for early detection of fraud and risk management. Java’s security feature proves beneficial when developing AI tools as this helps the AI systems to make sophisticated decisions about what can be considered fraud and what cannot.

Apache spark is used by leading banks and financial institution in fraud detection and management.

Trading applications

According to Oracle website, Java is the language of choice for electronic trading – providing a platform for rapid development, testing and deployment that underpins fast time to market. More than 80% of electronic trading applications are written in Java, including most FIX engines. The dynamic run-time compilation optimization that the Java VM offers can, in many cases, result in programs that exhibit better performance than those statically compiled by a C++ compiler.Oracle / Sun Java Virtual Machine and the JRockit Real Time (JRRT) VM helps in maintaining low latency and thus smooth functioning of trading applications.

According to Enlyft website, there are about 500 companies which are using JRRT, out of which 7% are using in financial services like Trading.

Mobile Wallets

Mobile wallets are developed using AI and Java-based algorithms to help consumers make smart decisions while spending their money

Java usage in web application

According to w3tech, Java is used by 3.7% of all the websites as server-side programming language.
