question: public static int len ( String list , String delimiter , boolean ignoreEmpty ) { if ( delimiter . length ( ) == 1 ) return len ( list , delimiter . charAt ( 0 ) , ignoreEmpty ) ; char [ ] del = delimiter . toCharArray ( ) ; int len = StringUtil . length ( list ) ; if ( len == 0 ) return 0 ; int count = 0 ; int last = 0 ; char c ; for ( int i = 0 ; i < len ; i ++ ) { c = list . charAt ( i ) ; for ( int y = 0 ; y < del . length ; y ++ ) { if ( c == del [ y ] ) { if ( ! ignoreEmpty || last < i ) count ++ ; last = i + 1 ; break ; } } } if ( ! ignoreEmpty || last < len ) count ++ ; return count ; }
target:  returns count of items in the list
