In my criteria find it works find but I must say
in my instructions
the string is "Carrier='SpeedyAir',Origin='SFO'"
but what I do is populate my comboBoxes origin and destination with all origin and destination not allowing duplicates.
In my CriteriaFind I pass a string such as below:
String criteria = new String(origin+","+destination);
although its not the same but it works find I use the StringTokenizer an it works find but I dont have = as others have talked about
"Carrier='SpeedyAir',Origin='SFO'" Suns Example
"origin+","+destination" my example I dont search airlines specifically just origin and destination...
Is this OK??
Thanks Lisa

Lisa,
the specification mentions the format in which you have to pass the query string to criteriaFind method. Why would you want to change that ? Your approach may work but in my opinion you should not change the format of the query string unless you have a very good reason to do so.

I can appreciate that, should I hardcode the fields in then parse it with the String Tokenizer class???

Such as "Origin='FRA',Destination='SFO'"
Thanks Lisa

Lisa,
In your criteriaFind() method, you can use two StringTokenizer to break down the criteria into a whole bunch of key/value pair like Origin/SFO. You can then store those pairs in a vector or arraylist, and then pass it to your find() method for a linear search.
