Hi Pragya, welcome to javaranch!

Can you please post the source code which you are using. I think you should not face any problems. When you iterate over a HashMap, the Map.Entry is placed on the value stack. Then you can iterate over the values which will again be an ArrayList, so the array list will be placed on the value stack. Then again you can iterate over that array list using another iterator tag and so on...
 
It is sorta covered in the JavaRanch Style Guide.
