No, the JVM does not directly execute an overloaded main() method. When a Java application starts, the JVM looks specifically for the method with the signature public static void main(String[] args) and begins execution from that method only.
Key Points: • The JVM recognizes only public static void main(String[] args) as the entry point of a Java application. • Overloaded versions of main() can exist with different parameter lists. • The JVM never invokes overloaded main() methods automatically. • Overloaded main() methods can be called manually from the standard main() method. • Method overloading of main() is valid Java syntax but does not change the JVM startup behavior.
Example: A class may contain main(int x) or main(String arg), but the JVM will still start execution from main(String[] args).
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");
}
}Interview Tip: A concise interview answer is:
"No, the JVM executes only the standard public static void main(String[] args) method. Overloaded main() methods are not called automatically by the JVM, but they can be invoked explicitly from the standard main() method."
