Java is known as the "King of Programming Languages." Java is now the foundation for billions of apps and devices. Java is a programming language with a wide range of applications. To learn more about java, enroll in the course right now.

Let's take a look at each of these real-time apps individually-

1. Desktop graphical user interface (GUI) applications

Desktop apps are written in Java. To create these kind of apps, you can use Java APIs such as Swing, AWT, and JavaFX.
The AWT (Abstract Windowing Toolkit) interface is used to create window-based Java applications. Swing is an AWT-based graphical user interface widget toolkit that includes more complex components such as lists, trees, scroll panes, tables, and tabbed panels. Swing is a “java-based” application programming interface. Swing responds to all keystrokes, mouse clicks, and other events. JavaFX is the contemporary approach to create a desktop application in Java. JavaFX is a graph-based programming language that differs from Swings and AWT.
ThinkFree, Acrobat Reader, Antiviruses, Media Player, and more real-world examples of desktop GUI apps

2. Applications for mobile devices
The mobile application is designed for smartphones and tablets. Most smart gadgets and phones in today's world run on Android, which necessitates the use of the Java programming language for Android development. A cross-platform framework called Java Micro Edition (Java ME or J2ME) is used to design programmes that operate on all phones and smartphones.
The reason for utilising Java for Android app development is that the Java compiler converts Java classes into bytecode, which is then executed by the Dalvik Virtual Machine (DVM), an Android-specific virtual machine.
Simple Calendar, Photo and video gallery apps, Netflix, Uber, Tinder, Google Earth, QRReader, and other popular smartphone apps are just a few examples.
If you want to create Android apps, you must first learn the Java programming language through an online java course.

3. Applications in Science

A scientific application is one that has an impact on real-world circumstances and makes use of mathematics. Because of its rich characteristics, Java aids in the development of scientific applications.
Scientific applications, in general, comprise mathematical operations and scientific computations, and Java training in Delhi can assist you in becoming the ideal choice for designing these applications. For scientific applications, Java provides a safe, quick, and highly portable environment, which is a prerequisite for these applications.
Medical science, research, space science, aeronautics, and other real-world instances of scientific applications are only a few examples.

4. Web-based Applications
Struts, servlets, JSP (Java Server Pages) and JSF (Java Server Faces), Hibernate, Spring, and web servers like Resin, Apache HTTP web-server, Apache Tomcat, Adobe JRun, and others can be used to create web applications in Java.

Java may be used to create any type of web-based application.JSPs and Servlets are server-side components that aid in the development of the web application's business logic. Because JSP offers more functionality than a servlet, it is referred to as a JSP extension.
Java for web development offers excellent security and simple code, allowing for the creation of a wide range of applications in the areas of social security, health, insurance, and education.
Online forms, irctc.co.in, Gmail, shopping carts, Google Sheets, Google Slides, and other web-based apps are examples.
