Hello ;

Follow this URL and see under the topic 'Using Collections' for a begining. 

 http://www.salesforce.com/us/developer/docs/apexcode/Content/apex_qs_core_concepts.htm

 

Following also will help you.

 

List<String> myList = new List<String>();//Create a list of Strings
myList.add('Hello');//Add a string to string list
Set<String> mySet = new Set<String>();//Create a set of Strings
mySet.add('Hello');//Add a String to String set
List<Set<String>> setList = new List<Set<String>>();//Create a List of String Sets.
setList.add(mySet);//Add a set to the List of sets.
