How to serialize/de-serialize a String array.

Looking for a tip here. I want to take the list of selected String values from a SelectItem where multiple="true" and store them in a cookie. Then retrieve them from the cookie and restore the selection later.

I have the selected values as a String array. How can I serialize that to store as a String in the cookie and then deserialize back to an array?

Figured it out. channelCodes is my String array.

This encodes it to a String.

String savedChannels = JSON.encode(JSOHelper.arrayConvert(channelCodes));

This decodes the String back into a String array.

JavaScriptObject jso = JSON.decode(savedChannels);
String[] restoredChannels = JSOHelper.convertToJavaStringArray(jso);
