That will work just fine.

@OP: Keep in mind that if your ArrayList contains objects which do not have an overridden toString() method, you may not get your desired results.

Are you trying to display some type of floating point data? Is the error occuring when the JList is trying to display its contents?

If so, as Navy_Coder suggests you may need to override the "toString()" method of the object that is being displayed in the JList.

If this is not it, where in your code are you seeing this error?
