Given the IntListElement class below:

class IntListElement {

IntListElement(int value, IntListElement e) {

data = value;

next = e;

}

IntListElement next;

int data;

}

What does the program below print?

class IntListElementTest {

public static void main(String[] args) {

IntListElement list = null;

for (int i = 5; i < 10; i++)

list = new IntListElement(i, list);

mystery(list);

}

static void mystery(IntListElement list) {

if (list != null) {

mystery(list.next);

System.out.println(list.data);

}

}

}
