How to write program Map interface in collection ?

import java.util.*;
public class Where
{
    public static void main(String args[])
    {
   HashMap h=new HashMap();
      h.put(111, "ram");
           h.put(112, "neha");
    h.put(113, "hem");
     h.put(114, "sallu");
      Set s=h.entrySet();
      Iterator it=s.iterator();
      while(it.hasNext())
      {
     Map.Entry me=(Map.Entry)it.next();
        System.out.println("me.getKey():" +me.getKey());
        System.out.println("me.getValue():" +me.getValue());
       
        }   
   System.out.println();
}   
}   

output:-

for compile-
E:\sallu>javac Where.java
for run-
E:\sallu>java Where
me.getKey():114
me.getValue():sallu
me.getKey():113
me.getValue():hem
me.getKey():112
me.getValue():neha
me.getKey():111
me.getValue():ram
