Adding key values continuously

Question

Hi,
I want to add some key-values in a hashtable continuously i.e for example
Hashtable cv = new Hashtable();
cv.put(key1,value1); //added key-value
The next time I execute the above code, the previous value will not be there, but only the current value. I want both the previous value and next value.
i.e. cv should contain [key1=value1, key2=value2]
How to achieve this?
Please help me in this regard.
Thanks in Advance....

Hi,
What happens here is
class Dymmy {
private Hashtable cv = new Hashtable();
public void addValue(Object key, Object value) {
List values = (List)cv.get(key);
if (values == null) {
values = new LinkedList();
values.add(value);
cv.put.(key, values);
When I invoke the class first time cv contains [key1=value1]
When I invoke the class second time cv again contains [key1=value1] instead it should contain [key1=value1,key2=value2]
If I invoke it third time cv should contain [key1=value1,key2=value2,key3,value3] ...
