Constructor overloading using null in Java

Following is the simple code relevant to constructor overloading in Java. Let's have a look at it.

package temp;

final public class Main
{
    private Main(Object o)
    {
        System.out.println("Object");
    }

    private Main(double[] da)
    {
        System.out.println("double array");
    }

    public static void main(String[] args)throws Exception
    {
        Main main = new Main(null);
    }
}

In the above code, constructors are being overloaded in which one has a formal parameter of type Object and the other has the formal parameter of type double[] (array).


Main main = new Main(null);

One of the constructors is being invoked by the above statement which is using a null value as it's actual argument and the program is displaying the output double array on the console. How does the compiler resolve a specific constructor (or a method, if such is a case) dynamically at run time in such a situation?
