Here's a simple Java program demonstrating basic syntax:

// This is a comment
public class HelloWorld { 
  public static void main(String[] args) { 
    // Variable declaration 
    String message = "Hello, Java Beginner!"; 
    // Print to console 
    System.out.println(message);  
    // Conditional statement 
    if (message.contains("Beginner")) { 
      System.out.println("Welcome to your Java journey!"); 
    } 
  }
