list list=new arraylist(); list.add(adjlists.get(l).get(h)); list.add(adjlists.get(l).get(h+1));  for(list<integer> arraylist:adjlists) {    while (arraylist.containsall(list)) {     arraylist.set(arraylist.indexof(adjlists.get(l).get(h + 1) + 1), 1);    } } 

you can use collections.indexofsublist

    int = collections.indexofsublist(list, arrays.aslist(o1, o2));
