Hi

How can I get this to look like...

Audi Sedan 1958,
BMW St. Car 1951

public static void main(String[] args) {
        
        HashMap <String, String> resultList = new HashMap <String,String>();
        resultList.put("4711Due", "Audi" + " " + "Sedan" + " " + 1958);
        resultList.put("4711Trio", "BMW" + " " + "St. Car" + " " + 1951);
        
        System.out.println(resultList.values());    


    }

result: [Audi Sedan 1958, BMW St. Car 1951]

You already know how to get the values; all you need to do is find a way to iterate over them. I'm sure you can find a nice method if you look into the Collection Javadoc.

I tried with..

public static void main(String[] args) {
        
        HashMap <String, String> resultList = new HashMap <String,String>();

        resultList.put("4711Due", "Audi" + " " + "Sedan" + " " + 1958);
        resultList.put("4711Trio", "BMW" + " " + "St. Car" + " " + 1951);        
        //System.out.println(resultList.values());
        Set set= resultList.entrySet();
        Iterator iterator = set.iterator();
        while(iterator.hasNext()) {
            System.out.println(iterator.next());
        }
        

   }

result:
4711Due=Audi Sedan 1958
4711Trio=BMW St. Car 1951


but it should be without the key..?
Audi Sedan 1958,
BMW St. Car 1951

1) your Iterator now returns instances of Map.Entry<String,String>. You can get the value with one of its methods.
2) why did you switch from values() to entrySet()?

You may also want to check out the "enhanced for-loop" a.k.a. the "for-each loop".

Thanks Rob Prime ;-))

public static void main(String[] args) {      
        HashMap <String, String> resultList = new HashMap <String,String>();

        resultList.put("4711Due", "Audi" + " " + "Sedan" + " " + 1958);
        resultList.put("4711Trio", "BMW" + " " + "St.Car" + " " + 1951);

//        Iterator it = resultList.entrySet().iterator();
//        while(it.hasNext()) {
//           Map.Entry e= (Entry) it.next();
//            System.out.println(e.getValue());
//        }
        
        Collection<String> set= resultList.values();
        Iterator iterator = set.iterator();
        while(iterator.hasNext()) {
            System.out.println(iterator.next());
            //System.out.println(iterator.equals(set));
        }
   }

Please use more informative titles for your threads, and the code button; I have edited your last post so you can see how much easier it is to read.

Did you get the code to work? In the instance with the iterator which you commented out, try

      Iterator<Map.Entry<String, String>> it = resultList.entrySet().iterator();
        while(it.hasNext()) {
           Map.Entry<String, String> e = it.next();
           System.out.println(e.getValue());
        }

That should work. The second attempt at printing looks all right from here. I presume it worked? In fact you seem to have two decent solutions to your problem

Better to declare the Map as Map<String, String> resultMap = new HashMap<etc>(); That way you can swap to a different implementation very easily.
