It is possible.we can easily invoke a main() of a class from another class.

I show  u demo here.

//Class Test

public class Test

{

public static void main(String args[]) //Main Method which is

//Invoked by another class Testing

{

System.out.println("Test Class main() Method is Called");

}

}

//Class Testing

public class Testing

{

public static void main(String args[])

{

if (args.length!=0)

{

Test.main(args);// Main method of Test Class is Calling

}

}

}
