Hey sorry. There is a small correction to the above code

/**
Remove duplicates from ArrayList<String> without using Set
*/
private static void removeDuplicates (ArrayList<String> al) {
for (int i=0;i <al.size(); i++) {
int index = al.lastIndexOf(al.get(i));
while (index != -1 && index != i) {
al.remove(i);
index = al.lastIndexOf(al.get(i));
}
}
}
