java - Convert Map to Sorted List -


I try to convert a map to an ordered list Based on the values ​​in the map

Suppose I have the following: 

  Maps & lt; String, integer & gt; Map = maps.newHashMap (); Map.put ("foo", 1); Map.put ("boo", 3); Map.put ("bar", 2); // List integer value - List of ASC or DESC & lt; String & gt; List = // elegant guava call? The list should be: {foo, bar, boo}    
 
 
  list & lt ; String & gt; List = ordering Natural (). OnResultOf (functions .map) .sortcopy (map.keySet ());   
 ... I think?

mongodb - CakePHP paginator ignoring order, but only for certain values -
