Question

hey,
i have a dictionnary like
“key2″,”value2”
“key3″,”value3”
“key1″,”value1”

is it possible to sort it on value ?
If not, any other object can do same thing? (sort value on key/value pair)

Answer 1

Well, clearly you’re talking about a Map.

It really depends on what Map you’re using, You don’t need to sort a TreeMap, coz it is already sorted.

For any other, You can get the keys using map.keySet() and use Collections.sort() to sort them. (Note, the map will remain the same, you’ll get a Set containing all the key values)

Hope it helped.
