I have a problem at 11_13,
if there are three continuous 4, the output list will have two 4s.
I think, for example, j is 5 now. After removing num1 of 5th, the num2 of 6th will move to 5th. Then j++. It leads to that num2 was passed. In other words, the for loop skiped some elements.
Change it toif(...){..} else{ j++;} may be worked. It will j++ only if if-condition is false.

/* i have a solution for this */
public static void removeDuplicate(ArrayList list) {
for (int i = 0; i < list.size(); i++) {
Integer obj = new Integer(list.get(i));
while (list.lastIndexOf(obj) != -1 && list.lastIndexOf(obj) != list.indexOf(obj)) {
list.remove(list.lastIndexOf(obj));
}
}
}
