Hi,



Q. Why does the code above compiles with the following warning??

Note: TestMaps.java uses unchecked or unsafe operatio
Note: Recompile with -Xlint:unchecked for details.

Ravinder-

I would guess that the warning you are getting relates to the fact that the collections and interator that you are using aren't type safe. Try making your TreeSets and your Iterator type safe and I think you'll see the warning disappear.



Hope that helps.

Thanks Joshua..
The warnings disappear if I change the statement for TreeSet instantiation to: TreeSet<String> map = new TreeSet<String>();

For the next time...compiler told you.

"Recompile with -Xlint:unchecked for details."

Sometimes it is useful to do, what compiler tells you.
