            if (stopwords.get(j).e         


        

Answer 1

Ok this is very good problem to solve. Lets start with an exmaple

We have data = [5,2,7,3,9,34,63,23,85,23,94,7]

indexes to remove

int index[] = [5,2,7,9]

Note : As you remove single item from array other elements get shifted by 1.

If we use ArrayList to remove elements of indexes then first you need to sort the indexes in descending.

i.e indexes = [9,7,5,2] then remove the element from index

ArrayList data = Arrays.asList(new Integer[] {5,2,7,3,9,34,63,23,85,23,94,7});

for(int i=0;i
