Olá, Hugo!
O método put da Hashtable não recebe (int,int), e
sim Objects
By API:
put
public Object put(Object key,Object value)
Maps the specified key to the specified value in
this hashtable. Neither the key nor the value can be null.
The value can be retrieved by calling the get method with a key that is equal to the original key.
The value can be retrieved by calling the get method with a key that is equal to the original key.
