how to use sortedmap interface in java

Question

How can I use sortedmap interface in Java? Can someone tell me an example

Answer 1

To implement a sortedmap you have to use TreeMap.

Here is an example for this:

Map<Integer, String> map = new TreeMap<Integer, String>(); 

 map.put(1, "Delhi");

 map.put(2, "Mumbai");

 map.put(3, "Bangalore");

for (Map.Entry<Integer, String> e : map.entrySet())

 {

 System.out.println(e.getKey() + " => " + e.getValue());

 }
