I need to sort my HashMap according to the values stored in it. The HashMap contains the contacts name stored in phone.
Also I need that the keys get automatically sorted as soon as I sort the values, or you can say the keys and values are bound together thus any changes in values should get reflected in keys.
HashMap<Integer,String> map = new HashMap<Integer,String>();
map.put(1,"froyo");
map.put(2,"abby");
map.put(3,"denver");
map.put(4,"frost");
map.put(5,"daisy");
Required output:
2,abby;
5,daisy;
3,denver;
4,frost;
1,froyo;
