Implementation within the Interface - Java

We know that we can't implement functions in interfaces in java.

I just tried 

public interface InvoiceService {
public static void getData(){
 System.out.print("this is my data");
 }
}

I am able to execute this function, why is it like that? is it because the function is defined as static and static variables can be accessed using class name directly without creating an object?

  • default method is another type of method that is allowed in interfaces in Java8. They contain a body and can be overridden by implemented classes. However static methods cannot be override. Commented Sep 15, 2015 at 9:04
