The below program prints CC. How? Why its not giving ambiguity error? How null gets type casted into C.




Sorry for not using the Code tag before posting this post. Post Updated as per your recommendations.

When the Java compiler has to choose between a number of alternative methods that match a method call, it will choose the most specific one, if there is no ambiguity. In this case, the method that takes two Cs is the most specific one.

For the exact details see the Java Language Specification, paragraph 15.12.2.5: Choosing the Most Specific Method.
