What is the purpose of the main() method in Java?

The main() method in Java serves as the entry point for any Java program. It is where the program begins execution. Here are some key points about the main() method:

1. Signature: The method is defined with the following signature:

   public static void main(String[] args) {
       // code goes here
   }

2. Public: This means the method can be accessed from outside the class.

3. Static: The method belongs to the class itself, not to any specific instance of the class.

4. Void: This indicates that the method does not return any value.

5. String[] args: This parameter allows the method to accept command-line arguments, which can be used to pass information to the program when it is executed.

In summary, the main() method is essential for starting the execution of a Java application.
