question: private int count ( boolean [ ] arraySetted , byte [ ] [ ] array , byte [ ] value ) { if ( value != null ) { int counter = 0 ; for ( int i = 0 ; i < array . length ; i ++ ) { if ( arraySetted != null && arraySetted [ i ] && Arrays . equals ( value , array [ i ] ) ) { counter ++ ; } } return counter ; } return 0 ; }
