Answer 1

when i=1

list.add(s1); cause "pull" to be added to list at end and size increased. size=3

when i=3

list.add(s1); cause "pull" to be added to list at end and size increased. size=4

when i=4

list.add(s1); cause "pull" to be added to list at end and size increased. size=5

This gets repeated.

But if you remove, size won't change because you adding again so size-1+1. When I=3 loop terminated

Answer 2

Your loop will run into infinite times as adding to list.add("pull") cause list.size() value also gets increased because if condition is always true. And it repeats every iteration....
if you remove and add, then list size is 3 only..

You are removing then adding same thing so every time size will be same.

If you will not remove then list size will be increase and result would be OutOfMemory

Answer 4

If you add list size is also increased!!
