Writing your first Java program is a foundational step to understanding Java syntax, structure, and execution.
It introduces you to the basic components of a Java application and how to compile and run Java code.

The “Hello World” program is traditionally the first program written when learning a new programming language.
In Java, this program demonstrates the structure of a class, the main method, and output to the console.
public class HelloWorld {
public static void main(String[] args) {
System.out.println("Hello, World!");
}
}
This simple program prints “Hello, World!” to the console.
Foundation for building command-line tools and utilities.
Essential first step in mastering Java programming language basics.
Build on this basic structure to create complex Java applications.
The main method is the entry point of any Java application. The JVM calls this method to start program execution.
System.out.println is used to print messages or output to the console, which helps in displaying information or debugging.
The class name defines the blueprint of the program and must match the filename for public classes.
