A warning occurs when an object is cast to an array (ArrayList) type, such as:

Infos = (arraylist<videoinfo>) data.getdata ();

because an object is converted to an array type, it is not checked for a certain risk.causes the array object to be cast, asArraylist<?> it is easier to control risk.
However, in order to write simple and adaptable to other nonstandard interfaces, it is possible to do so. Warning Suppression (suppresswarning)can be done before method, i.e.

@SuppressWarnings ("Unchecked")
