question: public static boolean moveUp ( Alignment alignment , int firstRow , int lastRow ) { lastRow = Math . min ( lastRow , alignment . getNumberOfSequences ( ) ) ; if ( firstRow <= 0 || firstRow > lastRow ) return false ; else { Integer [ ] array = new Integer [ alignment . getNumberOfSequences ( ) ] ; for ( int i = 0 ; i < alignment . getNumberOfSequences ( ) ; i ++ ) array [ i ] = alignment . getOrder ( i ) ; int replaced = array [ firstRow - 1 ] ; System . arraycopy ( array , firstRow , array , firstRow - 1 , lastRow + 1 - firstRow ) ; array [ lastRow ] = replaced ; alignment . setOrder ( Arrays . asList ( array ) ) ; return true ; } }
target:  move the selected interval of sequences up one
