The "Hello, World!" program is the simplest way to introduce Java programming. It demonstrates the basic structure and syntax of a Java program. Below is the code for the program, followed by an explanation of its components.

Code Breakdown

1. Class Definition: public class HelloWorld { ... } Every Java program begins with a class definition. Here, HelloWorld is the name of the class. The class name must match the filename (e.g., HelloWorld.java).

2. Main Method: public static void main(String[] args) { ... } This is the entry point of any Java application. The Java Virtual Machine (JVM) starts executing the program from this method. Keywords: public: Makes the method accessible from anywhere. static: Allows the method to run without creating an object of the class. void: Indicates that the method does not return any value. String[] args: Accepts command-line arguments as an array of strings.

3. Print Statement: System.out.println("Hello, World!"); This line prints the text "Hello, World!" to the console. Components: System: A built-in class from the java.lang package. out: A static member of the System class, representing the standard output stream. println(): A method that prints the given text and moves the cursor to the next line.
