question: public boolean containsSymbol ( String symbol ) { int bucket = hash ( symbol ) % fTableSize ; int length = symbol . length ( ) ; OUTER : for ( Entry entry = fBuckets [ bucket ] ; entry != null ; entry = entry . next ) { if ( length == entry . characters . length ) { for ( int i = 0 ; i < length ; i ++ ) { if ( symbol . charAt ( i ) != entry . characters [ i ] ) { continue OUTER ; } } return true ; } } return false ; }
