Using get method on hashtable

Question

I have built two hashtables and populated them with my data, but now I need to get the key from one table and see if it exists in the other, I've seen the get method in the api but I can't understand how to use it? Could someone show me a simple example of how to use the get method?

Do you have Hashtable or HashMap or a datastructure of your own? They're both Hashtables:
     Hashtable<String, String> activeData;
     Hashtable<String, String> passiveData;I've written this piece of code, not tested it yet though:
     public void doComparison(Hashtable<String, String> activeData, Hashtable<String, String> passiveData)
          Enumeration<String> e = activeData.keys();
          Enumeration<String> f = activeData.elements();
          while (!activeData.isEmpty())
               activeData.get(e);
               if (passiveData.containsKey(e))
                    //Keys match, now check data
                    activeData.get(f);
                    if (passiveData.containsValue(f))
                         //Both key and value matched
                         passiveData.remove(e);
                         passiveData.remove(f);
                         activeData.remove(e);
                         activeData.remove(f);
                    else
                         //The keys matched, but the data linked to them did not
                         //Call the output class here
                         passiveData.remove(e);
                         passiveData.remove(f);
                         activeData.remove(e);
                         activeData.remove(f);
               else
                    //Keys did not match, output the differences
                    //Call the output class here
                    passiveData.remove(e);
                    passiveData.remove(f);
                    activeData.remove(e);
                    activeData.remove(f);
