[Subho]

Hi,
1. Class Example {
2. public static void main(String args[]) {
3. Short s = 15;
4. Boolean b;
5. b = (s instanceof Short);
6. b = (s instanceof Number);
7. }
8. }

In the above given line of code can anybody tell where(line
number) autoboxing is happening and how???

Thanks in advance,

On lines 3, 5 and 6.

3. Short s = new Short(15);
5. b = new Boolean(s instanceof Short);
6. b = new Boolean(s instanceof Number);

OP, if you are having trouble with the "how" part, seek advice from your
professor or a classmate.
