Can we overload the main method?

Yes, the main() method can be overloaded in Java by defining multiple methods with the same name but different parameter lists. However, the JVM always starts program execution by calling the standard main method with the signature public static void main(String[] args).

Key Points: • Method overloading is achieved by changing the number, type, or order of parameters. • The main() method can have multiple overloaded versions within the same class. • The JVM recognizes and invokes only the standard main(String[] args) method as the entry point. • Overloaded main() methods can be called explicitly from the standard main() method. • Overloading main() is valid Java syntax but is rarely used in real-world applications.

Example: A class can contain multiple main() methods with different parameters, but the JVM starts execution only from the standard main(String[] args) method.

Code Example:

public class Main {

    public static void main(String[] args) {
        System.out.println("Standard Main Method");
        main(100);
    }

    public static void main(int number) {
        System.out.println("Overloaded Main Method: " + number);
    }
}

Interview Tip: A concise interview answer is:

"Yes, the main() method can be overloaded by changing its parameter list. However, the JVM always invokes only the standard public static void main(String[] args) method to start program execution."
