About Question com.enthuware.ets.scjp.v6.2.84 :

Post by devlam »

I did some checks on the behaviour of Arrays.asList() method and found that when you invoke it with a primitive-array it returns a List with primitive arrays (for example List<int[]>) whereas the invocation with an array of a certain object-class it returns a List of that object-class (for example List<String>).

Do you know why they implemented it this way? I was expecting also a List<int> as return value.

No, I do not know why it is that way. The API designers would be the best people to answer that.

I think it's not API designers implementation, but Java's generic method + varargs specification.
