Can there exist two main methods in a Java program?

Question

Can there exist two main methods in a Java program?

Only by the difference in their arguments like:

public static void main(String[] args)
         


        

Answer 1

The answer is Yes, but you should consider the following 3 points.

1. No two main method parameter should be the same

   Eg.

   • public static void main(int i)
   • public static void main(int i, int j)
   • public static void main(double j)
   • public static void main(String[] args)

2. Java’s actual main method is the one with (String[] args), So the Actual execution starts from public static void main(String[] args), so the main method with (String[] args) is must in a class unless if it is not a child class.

3. In order for other main methods to execute you need to call them from inside the (String[] args) main method.
