What is the Role of Java in the IT Industry?

The IT industry, especially in India, heavily uses Java in most of their projects.

Being a Java developer, one should have the knowledge about the Java-based tools and technologies used by the most of the IT industries such as Android application development, Web Development, etc. Because of this reason, this article focuses mainly on the Java tools and technologies used in different fields.

Classification of Java Tools/Technologies Based on Different Fields

1. Web Development

Web development refers to the development of a website(collection of web pages) or a web application(collection of smaller apps/modules..similar to a website). For example:- The site you are currently viewing is a website.

Server Side Technologies

To collect the data from the frontend and then give it to the logic layer and after processing giving back the response to the frontend is the work of the backend. This comes under server-side technologies.

  • Spring Framework
    This framework provides a way to develop a scalable web application using MVC(model-view-controller) architecture. Around 60% of IT industries use Spring. Spring also provides standard security measures.
  • Spring Boot
    Spring boot is the most used framework which reduces the headache of doing all the configuration like that in Spring.
  • Grails
    It is a rapid application development framework built on top of Spring. It provides some advantages of spring and rapid development environment of groovy to the user. Also, it has outstanding community support.

Java Application servers

The server is basically a system that processes the HTTP requests(example:-www.geeksforgeeks.com) and returns a response(can be a web page or data). Some of the most famous local servers used with Java frameworks are given below:-

  • Tomcat
    Tomcat is the most popular Java application server. There is a Java standard for a Web Application Archive file – aka WAR file. These are deployed to Application servers such as Tomcat to provide the run time environment for your web application. Also, Java applications can be deployed on the cloud as well.

2. Android Application

Android applications are .apk applications which run on Android devices. More and more devices are having Android kernel nowadays. So, it is also a good career option.

IDEs/Tools for Android application development

Following are some tools which provide rich interfaces for android application development.

  • Android Studio
    It has really brought a revolution in the world of Android development. With its features for debugging, testing and drag and drop option for frontend it is widely used today within a large community.
  • Eclipse
    It is one of the most famous IDE(integrated development environment) to work on Java based technologies. It has wide support of plugins for various activities including Android development.
  • AVD Manager
    AVD Manager is an Android emulator.
  • IntelliJ IDEA
    Just like Eclipse and Netbeans, it is also a very famous Java Development Tool.

3. Big Data

As the data is growing day by day, the appropriate handling of data has become necessary for every organization. Be it training the statistical model or anything else, handling big data isn’t easy and hence requires some tools for the same.
Some of them are given below.

Tools for big data

Just like Python, Java also provides some incredible tools for Big data analytics.

    It is an open source tool built over Java and is used for storing and processing large data. It is very widely used today.
  • Spark
    Spark is used to stream huge data and distribute batch.
  • Kafka
    Kafka is used for queueing large volumes of information.
  • Cassandra
    Cassandra is used for querying and storing Big/huge Data.
  • Spring Boot
    Spring Boot is used to provide the system’s options to the customers via REST API. Although it is a backend framework, it can be combined with other tools for big data analysis.
  • Elasticsearch
    Elasticsearch is used to store and query bulk volumes of information.

4. DevOps

Java DevOps is simply following the DevOps practices and philosophies for Java app development to obtain better and rapid development.

Some of the procedures you should know are:
