Say we have a Map:

Map
    
      m = new HashMap
     
      (); m.put("Hello", "World"); m.put("Apple", "3.14"); m.put("Another", "Element");
     
    

The keys as a List can be obtained by creating a new  from a  returned by the  method:

List
    
      list = new ArrayList
     
      (m.keySet());
     
    

While the values as a List can be obtained creating a new ArrayList from a  returned by the  method:

List
    
      list = new ArrayList
     
      (m.values());
     
    

The result of getting the List of keys:

AppleAnotherHello

The result of getting the List of values:

3.14ElementWorld
