Hi,

very short and simple:

// create a hash table
Map<keytype,>> myMapOfLists = new HashMap<keytype,>>();

// i.e. you and the Key to be a String and the Lists containing objects of type Person
Map<string,>> familyMap = new HashMap<string,>>();

// now get a list:
List<person> personList = familyMap.get("The Robinsons");

</person>

Hope this will give you a quick Idea... Actually, there are different types of Maps but since you want a Hash -> HashMap is the one you need...
