Introduction to Java Programming Language
Java is a powerful and versatile programming language used for developing software that runs on mobile devices, desktop computers, and servers.
- Simple syntax based on C++ but simplified and enhanced.
- Object-oriented design from the start.
- Distributed computing capabilities built-in.
History of Java Development
The Java programming language was developed by James Gosling at Sun Microsystems in 1995. Initially named “Oak,” it was later renamed Java when released publicly. The full history can be found here:

Key Characteristics of Java
- Simple Syntax Based on C++
- Object-Oriented Design
- Distributed Computing Capabilities
- Interpreted Execution via Bytecode
- Robustness with Strong Type Checking

Java is a fully‑featured, general‑purpose programming language that can be used to develop robust, mission‑critical applications. Today, it is employed not only for web development but also for creating standalone applications across various platforms — including servers, desktop computers, and mobile devices. Java was used in developing the code for communication and control of a robotic Mars rover.
Sample Java Program
public class HelloWorld {
public static void main(String[] args) {
System.out.println("Hello, World!");
}
