Description Phuoc Diec CLA 2004-05-24 09:05:24 EDT 
Got a warning message when edit a program with ArrayList as below:

ArrayList fileQueue = new ArrayList();
fileQueue.add(new File(startDir));

The warning message is:

Unsafe type operation: Should not invoke the method add(E) of raw type
ArrayList. References to generic type ArrayList<E> should be parameterized.

NOTE: The program was successfully compiled using ant

Eclipse 3M9 with Cheetah on Windows XP SP1.
Eclipse is started with jre 1.4.2_03

This is just a warning indicating you that you are using generic types without 
specifying type arguments. ArrayList is now meant to be used as: 
ArrayList<File> in your example. See the 1.5 spec draft about these.

You can turn off this optional warning in the compiler preference page (under 
1.5 tab).
