I was developing the below class and when I execute the below class I get the following result.. 

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

    private Confusing(double[] dArray) {
        System.out.println("double array");
    }

    public static void main(String[] args) {
        new Confusing(null);
        // new Confusing((Object)null);
    }
}

Output :-

double array

could you please explain why the outcome is of double array on console.

 Confusing(null)

method call goes to the most specific method

and here its 

private Confusing(double[] dArray)

as double[] reference is more specific than genericObject reference

The most specific applicable overload is used.

In this case the most specific is double array thus you get "double array" as output
