Dear friends, I have created a HashMap with no type specifications. HashMap hashmapObj = new HashMap(); But i want to put values with more than one type. For example. hashmapObj.put("key1",StringValue); hashmapObj.put("key2",ArrayListValue); hashmapObj.put("key3",InetgerValue); etc., When i do like this, compiler produces a warning regarding type safety. How to handle this without any warnings. I have a condition that i must return only one HashMap object. Kindly provide your help. Regards, Vijay

Just create the map like this: Map<String, Object> map = new HashMap<String, Object>();
