How to sort a HashMap in Java [duplicate]

Answer 1

Sorted List by hasmap keys:

SortedSet keys = new TreeSet(myHashMap.keySet());

Sorted List by hashmap values:

SortedSet values = new TreeSet(myHashMap.values());

In case of duplicated map values:

List mapValues = new ArrayList(myHashMap.values());
Collections.sort(mapValues);

Good Luck!
