HashMap<String,Integer> obj = new HashMap<String,Integer>();
obj.put("battipati", 1);
obj.put("Sai", 2);
obj.put("Nagendra", 3);
obj.put("Bhavani", 4);
obj.put("Prasad",5);
Iterator it = obj.entrySet().iterator();
while(it.hasNext()){
Map.Entry a = (Map.Entry) it.next();
System.out.println("The values are  " +a);
System.out.println(a.getKey() + " = " + a.getValue());
}
