we can use multiple main methods in a class by overloading
and not by the overriding. but the overriding is possible
in case of parent child combination.

example:
class xxx{

public static void main(String args[]){}
void main(){}
}
the above is called overloading.

example2;
class xxx{
public static void main(String args[]){}
}
class yyy extends xxx{
public static void main(String args[]){}
}
the above is overriding.
example3;
class xxx{
public static void main(String args[]){}
public static void main(String args[]){}
}
the example3 is not possible
}
