getting Employee Object out of HashMap

[fischen]

What is I want to do is retrieve a value out of a hashmap, the value is an Employee Object stored in an ArrayList.

? How do I accomplish this?

=========== here's my psuedocode ========

read employee.file into an strLineArray
split the strLineArray into ID, FirstName, LastName, and Phone fields;

Employee employee = new Employee(ID, FirstName, LastName, Phone);

ArrayList directory = new ArrayList();

directory.add(employee);

lastNameMap = new HashMap();

lastNameMap.put(new String(lastName), directory);
===================================

Question: how do I get an employee out the lastNameMap, given a lastName information?

Can someone also verify that I .put the directory (ArrayList) in the lastNameMap?

Thanks a bunch,
Fischen
