What is Java Programming

Our comprehensive Java programming tutorial is tailored for both students and professionals, providing a solid foundation in this versatile language. Java, renowned for its object-oriented, class-based, concurrent, and secure nature, stands as a cornerstone of modern computer programming.

Java, as both a programming language and platform, offers a high level of robustness and security, making it a preferred choice for a wide array of applications. Initially developed by Sun Microsystems, now a subsidiary of Oracle, in 1995, Java was conceptualized by James Gosling, often referred to as the father of Java. Originally named Oak, the language underwent a name change due to trademark concerns, ultimately adopting the moniker “Java.”

Distinguished by its runtime environment (JRE) and extensive application programming interface (API), Java serves as a versatile platform for software development. Let’s delve into a simple Java programming example to illustrate its functionality:

class Simple{
public static void main(String args[]){
System.out.println("Hello Java");

Java finds widespread application across various domains, powering an estimated 3 billion devices worldwide. Its versatility is evident in applications ranging from desktop software like media players and antivirus programs to web applications such as and Additionally, Java fuels enterprise applications, mobile development, embedded systems, smart cards, robotics, and gaming platforms.

In Java programming, applications typically fall into four main categories:

  1. Standalone Application: Also known as desktop or window-based applications, these traditional software installations are utilized independently on individual machines. Examples include media players and antivirus programs, leveraging Java’s AWT and Swing libraries.
  2. Web Application: Operating on the server side, web applications dynamically generate web pages. Technologies like Servlet, JSP, Struts, Spring, and Hibernate facilitate the creation of dynamic web content in Java.
  3. Enterprise Application: Distributed in nature, enterprise applications, such as banking systems, boast features like robust security, load balancing, and clustering. Java Enterprise Edition (Java EE) with technologies like EJB is instrumental in developing such applications.
  4. Mobile Application: Developed for mobile devices, mobile applications leverage platforms like Android and Java ME to deliver versatile and user-friendly solutions.

Java offers distinct platforms or editions catering to diverse development needs:

  1. Java SE (Standard Edition): Encompassing core Java APIs and fundamental concepts like Object-Oriented Programming (OOPs), multithreading, I/O operations, and GUI development using AWT and Swing.
  2. Java EE (Enterprise Edition): Tailored for web and enterprise application development, incorporating technologies like Servlets, JSP, EJB, and JPA.
  3. Java ME (Micro Edition): Focused on mobile application development, offering a streamlined platform for creating applications for mobile devices.
  4. JavaFX: Facilitating the development of rich internet applications with its lightweight user interface API.
