Dear Mr. Sang,
I've a couple of questions.
1-I've been playing around in some native interfaces code and I found Some
code which I don't understand like , In Interface 'CharSequence'
there is a method 'codePoints()'
I don't get what is the *default* key word , what is '->' is it an operator
?
return StreamSupport.intStream(() ->
Spliterators.spliteratorUnknownSize(
new CodePointIterator(),
Spliterator.ORDERED),
Spliterator.ORDERED,
false);
also I understand that methods doesn't contain implementations , but I see
that there is an inner class defined inside the codePoints() method who
this come ?
2- In 'Java Collections framework' Presentation under Java Programming
course
slide 58 about Map Interface , there is an interface defined inside the map
interface ?! I don't get this.
// Interface for entrySet elements
public interface Entry {
K getKey();
V getValue();
V setValue(V value);
}
