The ArrayList Class Uses Generics, Which Are

The ArrayList class uses generics, which are:

A) parameterized types, meaning that the data type will be defined at the time a client class declares and instantiates an object of the class.
B) parameterized types, meaning that programmers must specify the class of the objects they use.
C) initialized types, meaning that programmers can design a code class without specifying the class of the objects they use.
D) None of these is correct.
