How does one convert a HashMap to a List in Java?

Question

In Java, how does one get the values of a HashMap returned as a List?

Answer 1

Collection Interface has 3 views

• keySet
• values
• entrySet

Other have answered to to convert Hashmap into two lists of key and value. Its perfectly correct

My addition: How to convert "key-value pair" (aka entrySet)into list.

      Map m=new HashMap();
          m.put(3, "dev2");
          m.put(4, "dev3");

      List<Entry> entryList = new ArrayList<Entry>(m.entrySet());

      for (Entry s : entryList) {
        System.out.println(s);
      }

ArrayList has this constructor.
