remove()

method of Set in this case would not be able to find short objects. That's because the subtraction of 1 has resulted in an Integer object, so all call to

remove()

method will return false.
So, at the end the set will have 100 short objects (from 0 to 99).

the (I-1) inside remove call returns an Integer, which causes this.
