A Basic Java Program to print "Hello World".

public class HelloWorld {
  public static void main(String[] args) {
    System.out.println("Hello, World!");
  }
}
 

public class HelloWorld {

This line declares a new class called HelloWorld. In Java, a class is a template for creating objects, and everything in Java is an object. The public keyword indicates that the class is accessible by any other class.

 

  public static void main(String[] args) {
 

This line declares the main method, which is the entry point for the program. The public static void part indicates that the method is public (accessible by any other class), static (belongs to the class itself, rather than an instance of the class), and returns no value (void). The main method takes an array of String objects called args, which can be used to pass command-line arguments to the program.

 

    System.out.println("Hello, World!");
 

This line uses the println method of the System.out object to print the string "Hello, World!" to the console. The println method prints the string and adds a newline character at the end.

 

}

This curly brace closes the main method.

}

This curly brace closes the HelloWorld class.
