question: protected void fillAndSort ( final int dim ) { for ( int j = 0 ; j < size ; j ++ ) { E e = get ( j ) ; minSorting [ j ] . first = e . getMin ( dim ) ; minSorting [ j ] . second = j ; maxSorting [ j ] . first = e . getMax ( dim ) ; maxSorting [ j ] . second = j ; } Arrays . sort ( minSorting ) ; Arrays . sort ( maxSorting ) ; }
target:  Fill the array with the dimension projection needed for sorting.
