unchecked error when compiling my previous project with the new jdk 1.6
After modifing my code which was written in j2sdk 1.4.2_09, the compiler throws a:
warning:[unchecked] unchecked call to the add(E) as a member of the raw type java.util.Arraylist.
Does any one know how to check the string being added, all necessary checks done before trying to load the ArrayList

Read about generics (which was introduced in java 1.5).
All code that looks like this:
ArrayList x = new ArrayList();
x.add("ABC");
will give this warning message.
Instead, you're supposed to write it like this now:
ArrayList<String> x = new ArrayList<String>();
x.add("ABC");
But the COST of going through your entire code, and add all these
tags may be too expensive. Instead, if your code works,
just ignore this warning message.
