question: public void add ( char [ ] keyword , byte id ) { int key = getStringMapKey ( keyword ) ; loop : for ( char ch : keyword ) { if ( ! Character . isLetterOrDigit ( ch ) ) { for ( int j = 0 ; j < noWordSep . length ( ) ; j ++ ) { if ( noWordSep . charAt ( j ) == ch ) continue loop ; } noWordSep . append ( ch ) ; } } map [ key ] = new Keyword ( keyword , id , map [ key ] ) ; }
target:  Adds a key-value mapping.
