JDK 1.5 Type Safety warning

[Saket Barve]

Hello,

I am getting type safety warning in my code, relevant part of which is reproduced below:

   
 
ArrayList itemAddArrayList = new ArrayList<MeasurementEvalSampleItemVO>();
ArrayList measEvalSampleItemList = sampleVO.getSampleItems();
MeasurementEvalSampleItemVO sampleItemVO =
  ( MeasurementEvalSampleItemVO ) measEvalSampleItemList.get(0);
itemAddArrayList.add(sampleItemVO); // Warning here!
 

The last line gives a warning stating:
"The method add(Object) belongs to the raw type ArrayList. References to generic type ArrayList<E> should be parameterized."

How does one get around this warning? The Quick Fix option in Eclipse doesn't seem to come up with very helpful options.

Instead of making the type of itemAddArrayList the raw type ArrayList, make it the same parameterized type you use on the right.

Thanks for the reply Keith, the issue is now resolved.

Hello,

To avoid -Xlint:unchecked,

List<Type> Obj=new ArrayList<Type>();

Class<Type> Obj=new Class<Type>();
Class<Type> Obj=new SubClass<Type>();

Interface<Type> Obj=new ConClass<Type>();

One can use ? ( wild char) in Left hand side of = ( Declaration ) but not in Right hand side.
