Hi All,

I have a problem while using the HashMap, the requirement is to retrieve the keys in the order I put them, I know that HashMap does not guarantee me the order, but it is been used in too many places in my project, hence it is a scary change to use a different collection, does anyone know any workaround to get over this??? please help ASAP

Hi,

you could use a list where you store the keys of your hashmap in the order you inserted them in the map.

You want a LinkedHashMap. It should be relatively simple to replace your existing uses of new HashMap() with new LinkedHashMap().

There is no way to know the order of insertion in a regular HashMap. As Jim suggested, change your code to use a LinkedHashMap instead (or if you're ambitious create your own mechanism to track insertions in some way).
