Hello, I am relatively new to Java, but I have a friend whose helping me however, I have run into a problem that he doesn't know how to fix. I get an warning when I compile, but it seems like everything is working still. The Warning says:

Note: [classpath...]/EditorGUI.java uses unchecked or unsafe operations.
Note: Recompile with -Xlint:unchecked for details.

As I said, it seems like my program still works, but is there some way to get rid of this warning? Am I doing something wrong? I found out which line causes the warning, and I googled the error, but as I'm somewhat new to Java, I was unable to take what I found and apply it to my program. Here is the different parts of code associated with the warning.

In the top part of my class where I declare all my variables, I declare this:

Code:

public ArrayList<TagInstance> bitmTags;
//TagInstance is another one of my classes, which I wish to create an array of

Then I instantiate the ArrayList later on.

Code:

bitmTags = new ArrayList<TagInstance>();

And finally, here is the line that causes the warning, because when I comment it out, I don't get the warning, but I need to use this function to make my program work like I want it to.

Code:

Collections.sort(bitmTags);

Is there something I am doing wrong, and is there some way to get rid of this warning, or should I just live with it, seeing as my program still works even when I get the warning?
