What is the advantage of declaring an ArrayList with a specified type?
What will be an ideal response?
AnArrayList can hold any type of object; adding a data type in angle brackets causes Java to check that you are assigning appropriate types to a list. You can omit the angle brackets and data type following the ArrayList class name, but you receive a warning that you are using an unchecked or unsafe operation.
