Answer 1

okurpants you incrementing but before adding element so it adds after word not before.

and using i<elements will skip added number of elements from last .
This way works fine.. check now..

for (int i = 0; i < marks.size(); i++) {
if (marks.get(i).length() == 4) {
marks.add(i,"****");
if (i+1 !=elements) //to not to skip last element
i++;
}
}

Answer 2

okurpants

marks.add(i,"****");

By this code, you are adding 4stars before a 1st 4char word. so then **** becomes your next (i+1) word. So again this above step gets repeated. so your checking length 4 for 1st 4length word by loop always.

And if you use arraylist.length instead of elemenrs (size)., it will become infilte loop..
Whenever you add a 4star word ,increment i . (i++), (when if i+1 != elements ) so it will search next word instead of 4stars.
