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>();
