Thread: Conversion Warning
- 10-10-2009, 07:58 AM #1
can u please tell me how to get rid of the following warning.
warning: [unchecked] unchecked conversion for the following code 2nd line.
ArrayList<LabelValueBean> ControlTypeOptions= new ArrayList<LabelValueBean>();
ControlTypeOptions.addAll(CommonUtil.getComboOptio ns(request,"RadioButtonValues", false));
This is a warning not an error, so your program should still compile. My question is: what does CommonUtil.getComboOptions return? My bet is it returns an ArrayList, not an ArrayList<LabelValueBean>.

thanks for ur reply............ u r correct, it returns raw type array list.
now my question is how to handle that warning?
Is there any conversion to LabelValueBean?
ArrayList<LabelValueBean> ControlTypeOptions= new ArrayList<LabelValueBean>(); ControlTypeOptions.addAll(CommonUtil.getComboOptio ns(request,"RadioButtonValues", false));
I don't know of any conversion. If this is not a method that you've created, and you can't make it return a generic ArrayList, you could turn the warning off via an annotation.

annotation means......... can u plz tell me clearly
give some code it possible.
It would be better to read the Sun tutorials on this or find examples via Google. No sense in me re-inventing things that are already better described than I am able to do. Much luck.
