Well, I think we are going out of the question. The question
is that whether there is any error if we have multiple main
methods. Answer is not necessarily. I would like to change
the question in this way. Will it be possible to have
multiple main methods in the same class? Now the answer is
YES. WE CAN. But there should be only one main method that
has the complete signature "public static void main(String
args[])".
For example,
class Test
{
public static void main(String args[]){....}
public static void main(int args[]){....}
public static void main(boolean args[]){....}
public static void main(Object args[]){....}
}
this code will work without any error.
Remember there should be ONLY ONE main method with the
signature "public static void main(String <varargs>)"
because the compiler searches for this method to be loaded
into the bootstrap loader. If there are multiple methods
with this signature, it will throw an error.
