In Java 25, you can take advantage of the classless main method, allowing you to write short and simple programs without needing to wrap them in a class declaration. This feature is designed to make Java more approachable, especially for quick scripting or beginner-friendly coding introductions.

How to Use Classless Main Methods

1. Create a Java file:
   Simply start with a .java file, skipping the need for a class declaration. Declare a void main() function as your entry point.

   Example:

   void main() {
      System.out.println("Hello, Java 25!");
   }
   

2. Run the file:
   Compile and run the program directly using the java command. Java 25 interprets this as an entry-point method.

   java Hello.java
   

3. Output:
   The program will execute, and you’ll see the result printed into the terminal:

   Hello, Java 25!
   

Key Details of Classless Main Methods

• No public class wrapper needed:
  There’s no need to define a class or include access modifiers like public.

• Focus on simplicity:
  This syntax makes it easier to write short utility scripts or test snippets without boilerplate.

• Direct script execution:
  Java 25 allows you to directly execute .java files without manually compiling (javac).

Use Cases

• Learning Java: Ideal for beginners who want to experiment with Java quickly, without worrying about object-oriented concepts initially.
• Script Writing: Great for quick scripts, prototyping, or throwaway Java programs.
• Debugging and One-Liners: Use it to test small snippets or explore functionality without creating entire project structures.

Java 25 is continuing to evolve into a flexible language both for large enterprise systems and small-scale scripting needs with minimal setup.
